Description Egmont Koblinger 2003-09-08 21:35:12 UTC
I have the sticky notes applet on my panel, and have a note on the screen.
I close all my applications except this sticky note, and then log out.
After confirming logout, a window telling that this panel has died
unexpectedly and asks whether I want the panel to reload it appears for a
very short time. (This is the same window as I get if I kill the
stickynotes_applet process.) Since metacity has already exited by this
time, this window appears at the top-left corner of the screen and is
unmanaged. The window appears for a really short time: rarely it doesn't
appear at all, sometimes only the gray background color appears (and then
X exits), but in most of the cases the text appears for about a tenth
of second before X exits. This time is only sufficient to read one or two
words of the text where I've previously focused my eyes, but it clearly
mentions the Sticky Notes applet (I had to logout 10--20 times to be able
to read it :-)).
This visually annoying bug doesn't cause any misbehaviour of the applet
and only seems to occur if I have at least one note on my desktop.
As it seems to be a bug of time conditions and races, it might be
important: I have Celeron 375MHz 384MB ram, Matrox G400 card, XFree 4.3.

Sorry, there's a typo...

After confirming logout, a window telling that this _applet_ has died
Comment 2 Luis Villa 2004-02-13 02:23:24 UTC
Hrm, I don't see this anymore. Are you still seeing it in 2.5, Egmont?
It's fairly embarassing if you do see it. [I'm seeing something else
at logout, also embarassing, but that's a different bug ;)
Comment 3 Madhan Raj M 2004-05-20 18:52:32 UTC
Gnome stickynotes_applet 2.6.1 
Egmont: Do u still see this bug?. I'm not able to reproduce this bug. It working fine. Infact after 
starting the xwindows again restores the sticky note applet exactly in the same form i left it 
during logout. 
So shall this bug be closed. 
Comment 4 Egmont Koblinger 2004-05-22 09:48:00 UTC
I still use 2.4.2 but plan to switch to 2.6 soon. I'll come back and tell what
I see there.
Comment 5 Sagar Rastogi 2004-05-31 06:20:52 UTC
I don't see this bug in 2.6
Comment 6 Dennis Smit 2004-06-04 08:56:48 UTC
I think this is fixed, can't reproduce either.

Egmont if it's still around after your upgrade, please reopen the bug

I'm closing for now

Thanks for reporting back!
Comment 7 Egmont Koblinger 2004-10-11 19:05:19 UTC
Sorry for being so slow, but I reopen it now, as the bug still occurs in 2.8.0.
Seems it's also related to #153269.
Comment 8 Vincent 2004-10-28 12:54:29 UTC
Confirmed that it still occurs on 2.8.0 (GARNOME 2.8.0). I come from bug #153269
where I originally posted my comments. I was not so lucky to be able to see
words from the dialog that pops up but symptoms are exactly the same.

Problem seems to occur when applet crashes before exiting (as Egmont says).
Effect is that notes' positions are not correctly remembered hence appearing all
on top of each other at startup (in upper left corner).

Note that I do not think it is related to the notes config file
(.gnome2/stickynotes_applet) because notes are incorrectly positioned 
_WHEREAS_ config file fields about position (x and y attributes) are properly
set. Maybe this occurs while parsing the config file ?
Comment 9 Danielle Madeley 2004-10-28 23:44:03 UTC
Ok, we're going to need backtrace (prefereably good back trace with symbols and
such). Without trying... here is the way I think you can get a backtrace while
logging out.

Start 'screen'. If you're not familiar with it, screen is like a session manager
for terminals.
Inside your new screen terminal, `killall stickynotes_applet`
Then before reloading run `gdb stickynotes_applet` and type 'r' to start running
the applet.
Reload the applet.
Log out.
GDB should catch the exception...
Go to a terminal (eg. vt 1) and type `screen -x` to reconnect your screen from a
second location. Ideally now you should be able to get a backtrace via 'bt'.

Of course, I haven't tried this, so your milage may vary.
Comment 10 Egmont Koblinger 2004-10-29 14:21:46 UTC
I tried this, this is what gdb said:
Program exited normally.
(gdb) bt
No stack.

I didn't see the popup window though.
And at the next login the applet was placed again at a wrong position
(as mentioned bug #153269.)

Sorry for the lame question, Davyd, but as you ask backtrace from others: does
sticky_notes work correctly for you (even regarding that other bug report)?
Comment 11 Danielle Madeley 2004-10-30 01:37:08 UTC
Egmont, to be perfectly honest due to time contraints I haven't had time to look
at this bug. I was kind of hoping that we would get a good backtrace and could
nail the bug without a lot of work on my part ;)

I'll try to have a look at it later on.

Upping the priority to ensure this is fixed for GNOME 2.10
Comment 14 Juan J. García de Soria 2004-11-24 08:54:51 UTC

I think we may be talking about an older, more general bug here.

I have now a Gentoo Linux with GNOME 2.8, and I'm seeing the "Sticky Notes
Applet does not remember notes position" of bug #153269, so I have removed the
applet from my GNOME Panel, because the notes were getting in my way when their
position was wrong.

I'm getting the grey box + warning now too, even with the sticky notes applet

But the actual thing is that I've been experiencing the "something broke at
logout" syndrome since the GNOME version supplied with Mandrake 9.2 at least
(GNOME 2.4).

I consistently get the grey rectangle at the top left corner of the screen at
logout and the "system-logout" sound is interrupted, and substituted for the
"system-warning" one.

Unfortunately I've not been able to read any of the messages even when putting
some background load on my CPU in any case, so I don't know what's getting
broken. I would bet on something going crazy either in gnome-session or gnome-panel.

I don't know anything at all about how the session is managed in GNOME, but...
May it have something to do with the applets being notified for session end
AFTER the GNOME Panel is notified and destroyed?

Comment 15 Juan J. García de Soria 2004-11-24 13:07:28 UTC
Tried to do the screen + gdb trick as sketched by Davyd...

First time killall seemed to kill two instances of sticky_notes, so I restarted
only one of them.

Then I've tried, and the gdb output says that the application had exited
normally.  Anyway the notes keep being misplaced.
Comment 16 James "Doc" Livingston 2004-12-05 02:45:11 UTC
I'm seeing this as well (on Fedora Core 3 x86). It seems happen about one in
every four logins, but as an interesting data point it doesn't seem to occur
when I reload the applet after a kill or kill -9.

I've gotten some backtraces (which I can attach if you want), but I doubt
they're going to help. They report a SIGPIPE, but every one gets its backtrace
cut off with a corrupt stack frame. Basically they goes: pthreads -> various X 
things  -> gdk -> two unidentified frames at high addresses -> gobject ->
corrupt stack frame.

If you think they'll help I can attach the backtraces, but they're not getting
as far up as the applet.
Comment 17 Kjartan Maraas 2005-01-03 16:46:11 UTC
Hmm, I remember seeing the grey rectangle in the upper left area on the screen
when running a gnome-session under valgrind. This was without the stickynotes
applet running at all so I don't think it's related to one specific applet or
maybe not even an applet at all.

It's barely noticable under a normal session and even when running under
valgrind I can't see any content in the grey area...

Comment 19 Luis Villa 2005-01-22 17:22:02 UTC
I saw this yesterday on a slow session; it was very clearly the notification
area- so maybe it is happening to multiple applets?

Federico, didn't we find/kill one of these for NLD9? Did that patch make it
Comment 20 shakti 2005-01-24 05:20:10 UTC
I am seeing it for volume-control applet but I couldn't able to read the warning
Comment 21 Jochen Eppler 2005-01-24 14:58:17 UTC
I am observing the same behaviour with the multiload-applet-2
Comment 22 Vincent Untz 2005-01-26 13:17:11 UTC
Isn't this a duplicate of bug #147691 ?
Comment 23 Egmont Koblinger 2005-01-26 13:44:08 UTC
No, I don't think so.
Comment 24 Vincent Untz 2005-01-26 14:10:33 UTC
Egmont: do you have any applet listed in ~/.gnome2/session?
Comment 25 Egmont Koblinger 2005-01-26 14:25:37 UTC
No, I don't even have this file since I never save the current session at
logout. /usr/share/gnome/default.session is the same as found in mainstream
gnome-session (there are 4 clients: gnome-{smproxy,wm,panel} and nautilus).
I can always easily reproduce the bug with brand new user accounts with empty
home directory as well as with my old account.
Comment 26 Arvind S N 2005-01-27 04:03:29 UTC
not sure how relevent it would be here but in the 2.0 days we had the same
problem with geyes applet crashing on logout. see bug #90547 . Mark fixed it
then. Wonder if something similar has re-surfaced.
Comment 27 Jens Granseuer 2005-02-04 08:38:19 UTC
Just for the record, I'd like to mention that I'm seeing frequent crashes of the
modemlights applet on logout (GNOME 2.8).

Comment 29 Filip Miletic 2005-02-23 16:41:32 UTC
Another report, FC3 (thus I guess Gnome 2.8) and sticky notes. The notes don't
remember their position. As far as I can see, this is due to the notes not
exiting properly. 

However, I never see a window reporting the crash.

I can remember that the notes used to work, but not at which GNOME version
though. Sorry.
Comment 30 Luis Villa 2005-07-10 04:36:33 UTC
Without being able to duplicate reliably I'm taking this off the showstopper
list. But god I hate this bug. :/
Comment 31 Danielle Madeley 2005-12-21 06:32:37 UTC
Is this still happening? Marking as NEEDINFO.
Comment 32 Egmont Koblinger 2005-12-21 11:12:09 UTC
For me this bug seems to be gone with gnome 2.12.0.
Comment 33 Danielle Madeley 2006-01-11 03:59:50 UTC
Closing, someone please reopen if it appears again.
