GNOME Bugzilla – Bug 662805
Gnome Shell killed by Signal frequenly
Last modified: 2011-10-31 17:51:13 UTC
Since 3.2.1, Gnome Shell is (according to /var/log/messages) "killed by signal" every 30 minutes or so without an apparent reasons. I use an up2date archlinux (x64) and it seems that I'm not the only one with this problem: https://bbs.archlinux.org/viewtopic.php?id=128150 (added .xsession-errors as attachment, let me know if you need more information)
Created attachment 200064 [details] my .xsession-errors
Do you have any extensions installed?
I had some extensions installed, but since this problem appeared I disabled all but Pidgin IM Integration (https://github.com/kagesenshi/gnome-shell-extensions-pidgin) and the Places Status Indicator Extensions. I disabled them both now, to see if they're causing the errors.
I'm also affected by this bug in Gnome 3.2. There is also a bug report in Ubuntu Launchpad about it together with a stack trace. As far as I can see, it's the same source problem: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/867645
The trace from the bug cited above is a failed assertion in gjs_object_instance_constructor() at gi/object.c:668: "assertion failed: (unthreadsafe_template_for_constructor.info == NULL || strcmp(g_base_info_get_name( (GIBaseInfo*) priv->info), g_base_info_get_name( (GIBaseInfo*) unthreadsafe_template_for_construct"...
+ Trace 228928
I also experienced those nasty crashes every 20 minutes with Gnome Shell 3.2.1 on Debian before downgrading to 3.0.2. I used no extension. The most pertinent lines I found in .xsession-errors were these: .... (gnome-shell:24033): Clutter-WARNING **: Attempting to add actor of type 'ShellGenericContainer' to a container of type 'StBoxLayout', but the actor has already a parent of type 'StBoxLayout'. (gnome-shell:24033): St-WARNING **: Actor of type 'ShellGenericContainer' is not a child of the StBoxLayout container ....
"Killed by signal" just means that GNOME Shell crashed. This specific backtrace is a duplicate of bug #661323. Tsu Jan, can you file a new bug? *** This bug has been marked as a duplicate of bug 661323 ***
> Tsu Jan, can you file a new bug? I'm not sure that what I encountered is really different from bug #661323, although I don't remember "ERROR:gi/object.c:671:gjs_object_instance_constructor: assertion failed" in xsession-error. Unfortunately I have to stick with GNOME-Shell 3.0.2 as I need a stable desktop for now.
