Comment 1 Vincent Untz 2006-01-16 21:01:07 UTC

Reinout: can you easily reproduce? Can you get a stack trace with debugging symbols?

Comment 2 Reinout van Schouwen 2006-01-16 21:43:09 UTC

It's reproducable 100% of the time (i.e. I'm limping by without a panel now). I'll try if I can build from cvs with debug on...

Comment 3 Reinout van Schouwen 2006-01-17 22:27:40 UTC

Unfortunately it requires cairo 1.0 and that isn't yet available on mandriva cooker, and I don't have the disk space or cpu power to do a full garnome/jhbuild.

Comment 4 Jose M. daLuz 2006-01-18 22:19:44 UTC

I have the same problem. I just recompiled Gnome 2.13.x with debugging info so hopefully the following backtrace will be useful. The problem goes away if I drop gnome-session from 2.13.5 or 2.13.4 to 2.12.0 but happens 100% of the time with either 2.13 version. I'm running Gentoo 2005.1/AMD64/xorg-x11-7.0/2.6.15-ck1.

Backtrace was generated from '/usr/bin/gnome-panel'

Comment 5 Christian Kirbach 2006-01-19 19:49:52 UTC

Jose, the last stack trace is a different one (meaning different problem)
please file a seperate report for it.

Done. Bug 327748 – gnome-panel-2.13.5 crashes on session startup

Comment 7 Vincent Untz 2006-01-20 22:11:09 UTC

Reinout: I'm quite surprised that cairo 1.0 is not in cooker, but I'm not a mandriva user, so...

The only way that it could happen is that bonobo_iid is not set for an applet in gconf. Could you do the following in gconf-editor, eg:

 * open gconf-editor
 * go to /apps/panel/applets
 * look at all subdirs and see if the bonobo_iid key is set there

Also, the content of /apps/panel/general/applet_id_list can be useful? Does all strings in there match a subdir in /apps/panel/applets?

I'm committing a patch that should avoid a crash caused by this.

Comment 8 Reinout van Schouwen 2006-01-20 22:33:04 UTC

I assume that this is purely a question of time and a newer cairo will be in soon. 

Anyway, I purged my panel configuration (it had gathered a LOT of cruft during the years) and the problem went away. If you have a patch to prevent a crash in this situation, we can close the bug.

Comment 9 Vincent Untz 2006-01-21 07:29:19 UTC

Ok, closing.
Thanks
