Comment 1 Thomas Thurman 2008-04-27 20:37:17 UTC 
This seems particularly weird to me.  Does the session manager spawn another instance of Metacity after the previous one dies?
Comment 2 Maciej (Matthew) Piechotka 2008-04-27 20:42:08 UTC 
No. As it lives. But it do not live ;)

To be honest I wander if it should not be 2 bugs:
- metacity crashed and/or closed 
- gnome-session do not handle this correctly (at least by handling signal - as described on wikipedia)
Comment 3 Thomas Thurman 2008-04-27 20:56:21 UTC 
Well, if Metacity crashed, that's definitely our problem, and if the session manager has a problem with Metacity crashing, that's the session manager's problem (even though Metacity should never crash).  Can you raise another bug for the session manager problem, mention its ID here, and retitle this one?

Also, I run evince quite a lot and Metacity's never crashed on me; can you enable logging and send the logs to one of the maintainers, or post them if they're not a security problem?

Comment 4 Maciej (Matthew) Piechotka 2008-04-27 21:07:52 UTC 
AD. 1: I'll do it in a second.

AD. 2: I had few problems with Gnome 2.23.x so I downgrade to 2.22. I repeat migration in a week and then I will make metacity logging (I use this computer for everyday work).

AD. 3: It's not evince. It happened 2 times with evince (with make me think so) and once without.
Comment 5 Maciej (Matthew) Piechotka 2008-05-26 13:44:21 UTC 
I've run the command:
% metacity --replace 2>&1 | tee metacity.log
And I'm wait. Is there any option which increase the verbosity?

I've reproduced bug yesterday. During logging the metacity output I've got a crashes - however properly habdled. I cannot reproduce it with 2.23.13.

I'll reopen if I reproduce. I hope I won't
Comment 7 Maciej (Matthew) Piechotka 2008-05-30 12:58:11 UTC 
Just reproduced in 2.23.13. I run this command and I'm waiting...
Comment 8 Thomas Thurman 2008-05-30 13:07:12 UTC 
(I'm leaving this as NEEDINFO until one of the maintainers gets some logs, though, since we do actually still need info from you)
Comment 9 Maciej (Matthew) Piechotka 2008-05-30 13:29:59 UTC 
I know. I've stated that I'm starting logging. Is there any method of turning up the verbosity?

Reproduced in 2.23.34 - however it is much less frequent [first time since a long time].

In your version from 2.23.13, the error occurred inside this if statement:

  if (old_focus_win)
    {
      old_focus = find_window_for_screen (screen,
                                          old_focus_win->frame ? old_focus_win->frame->xwindow :
                                          old_focus_win->xwindow);
    }

The only obvious way that this can segfault is if old_focus_win->frame cannot be dereferenced.

This has been rewritten between 2.23.13 and 2.23.34, and some extra checks for nulls added.  If you can get us a backtrace of the problem in 2.23.34 (or even better trunk) it would be hugely useful.

I might to use the old version. After crash the only way I can check the version is to check it in package system. And since I rarly leave gnome...

I'll reopen if I reproduce it
