Description johnny 2006-07-04 08:34:54 UTC 
Distribution: Ubuntu 6.06 (dapper)
Package: gnome-panel
Severity: major
Version: GNOME2.14.2 2.14.x
Gnome-Distributor: Ubuntu
Synopsis: Gnome-Panel crashes when selecting Always on Visible Workspace
Bugzilla-Product: gnome-panel
Bugzilla-Component: Panel
Bugzilla-Version: 2.14.x
BugBuddy-GnomeVersion: 2.0 (2.14.1)
Description:
Description of the crash:
If you select "Always on Visible Workspace" on an application in the
task panel, gnome-panel will crash when you right click the button next
time. This has been verified with both a terminal and Beep Media Player.
I have also tried to reboot my computer and tested this with no other
applications running than one terminal window.

Steps to reproduce the crash:
1. Open any application (I tested with a Terminal window)
2. Right click the Terminal button in the Task Panel, and select "Always
on Visible Workspace".
3. Right click the Terminal button again, and gnome-panel crashes.
3. 

Expected Results:
The context meny should appear.

How often does this happen?
Every time I try

Exactly the same problem here, however I use Ubuntu Edgy Eft (6.10), and thus Gnome 2.16 instead of 2.14.

I'm seeing this on SLED as well, so it's not a complete Ubuntuism.

I can't reproduce this with gnome-panel 2.14.3 on Debian. Does upgrading to at least 2.14.3 fix the problem?






Comment 6


Sebastien Bacher

Do people having that problem use a patched libwnck for compiz?






Comment 7


Mark Gordon





          2006-12-14 19:12:34 UTC
        



That's the case for me on SLED. Package changelog excerpt:

* Tue May 30 2006 - danw@suse.de
- Patch in a new method from libwnck HEAD to allow compiz to know
  when a window has a real name (as opposed to a fallback name like
  "untitled window").

I can look into reproducing on an unpatched libwnck, if that's the patch you're suspecting is the problem.  We can also wait to hear whether Ubuntu users have a similar patch.  Awaiting further feedback.

all the ubuntu bugs reported on launchpad with a similar backtrace are happening to people who installed a un-official package patched for compiz, trying without that patch would be nice

I got the crash with 2.16.1-0ubuntu1.1 
Did not explicitly previously select "always in front" or "always on visible workspace"

For installing the -dbgsym debug package, I had to revert to 2.16.1-0ubuntu1 which does not exhibit the crash

advancing to 2.16.1-0ubuntu1.1  again and i can trigger the crash

seb128?

no patched libwnck here for compiz, I believe






Comment 11


Sebastien Bacher

Christian, Ubuntu has no such libwnck version: 2.16.1-0ubuntu1.1, that's the version used by people who provide a deb patched for compiz though. Where did you get it? What is the current changelog entry from that package?






Comment 12


Mark Gordon





          2006-12-26 14:02:39 UTC
        



I recently installed a libwnck with an updated patch for compiz and am no longer able to reproduce the bug.  I therefore feel quite confident in attributing my problems to the earlier patch for compiz.
