Description of problem: When certain applets, placed at the right of the panel (like the clock, or the systray^Wnotification area) resize themselves (e.g. I open an app with a tray icon) gnome-panel often crashes (I get a popup saying it has unexpectedly stopped working, anyway). Other particular culprits include GAIM, aMule etc etc. Not sure if it's related, but leaving xmms running for a while seemed to trigger it too, when I had the window-list menu on the panel too. I've completely blown away ~/.gconf (gconftool-2 --recursive-unset /apps, ditto /system, etc; then rm -rf .gconf after logging out of X). Still happens. Version-Release number of selected component (if applicable): gnome-panel-2.11.91-2 metacity-2.11.2-1 gnome-applets-2.11.91-2
Just crashed again as I hit the submit button in firefox to open the bug. It looks like sometimes just a change in a window title can trigger a crash too.
Never mind, seems to have been caused by two copies of libwnck on the system.
Yuck. No, it just didn't happen for a while. Just after gaim changed the tray icon (becuase I was marked away) the panel crashed again. And it's just done it again now (five minutes later) while I'm trying to type this. OK, what can I do to help track down the cause of this? Beyond "when I have anything changing state in the systray" I mean ...
Thanks for the bug report. Without a stack trace from the crash it is very hard to determine what caused the crash. Please see http://fedoraproject.org/wiki/StackTraces for more information about getting a useful stack trace.
I'll have a go, yes - just installing the -debuginfo packages now. I did click the "inform developers" button but the traces didn't look too useful :-S
Well, .. I installed all the debugingo packages, and I've attached gdb ... and it hasn't done it since :) It *did* crash while I was installing the debug packagess and running prelink, so I'm gonna write this off as bad luck for now :)
*sigh* done it again, I have a core dump this time. I'll try to attach it if 'zilla will accept the file.
Created attachment 117779 [details] core file from crashed gnome-panel. I don't know if this will help *that* much ... but I can't make enough sense of the data to make any deductions beyond "it looks like the menu change monitor" :) gnome-panel-2.11.91-2, from rawhide; I've prelinked everything, if that matters I can pass on a copy of the binary or undo prelinking and try again.
Please don't attach core files, attach a stack trace. See: http://fedoraproject.org/wiki/StackTraces Also, that core file was from gaim, not the panel.
i *think* i've been seeing the same thing, but it's only on newer (ie anything after 1469) kernels. i looked at, but didn't save, the stack trace from bugbuddy: #0 was in something that ended in 'vsyscall()' is all i remember. i'll get a full trace after yum is done.
ok .. how do I remove an attachment? and some output from gdb follows
Created attachment 117788 [details] some debug output from gdb + panel
Sorry, it seemed to me the trace alone didn't say much of any use -- the state of the variables at the time would perhaps explain the segfault, hence the core file :-S GAIM dies every time the panel does (presumably related to the tray icon, 'cause it survives the crash if I disable the icon). I just assumed the core file was from the panel 'cause I quit gdb with "signal 6" ... maybe I need to disable bug-buddy or whatever. Anyway, if there's any additional info I can prise out of the program state if/when it crashes again, please tell me, I'm running it with gdb attached. If it's helpful: last time it crashed, was when I updated a couple of packages; the next time I clicked on a launcher (the GAIM one, as it happened) *boom*
Looks like a gnome-menus bug which was fixed upstream recently: * Tue Aug 16 2005 Mark McLoughlin <markmc@redhat.com> 2.11.91-1 - Update to 2.11.91 - Backport patch from HEAD to hopefully fix crasher (rh #165977) Please re-open if you still see the problem with gnome-menus-2.11.91-1
Upstream bug report: http://bugzilla.gnome.org/show_bug.cgi?id=313232
Reopening due to regression. Whenever a menu is changed e.g. by installing / upgrading a package, two copies of all KDE menu items now appear.
Please don't re-open bugs with details of some other bug report. Open a new bug report. Thanks for testing, though. I assume this means the crash has been fixed? The new bug you're referring to is filed upstream at: http://bugzilla.gnome.org/show_bug.cgi?id=313624
Um, ok, ... the crash is gone, but the menus are still messed up; I thought it best to report that in case it's related ... I take it there's no need to open a new bug on brc if it's in gnome 'zilla and will be fixed in the next upstream bump?
Bill: please test gnome-menus-2.11.91-2 now - the "duplicate entries on updating" issue should be fixed. If you still see that issue or any other new issues, please do open another bug. Thanks.
gnome-menus-2.11.91-2 had an infinite loop, fixed in gnome-menus-2.11.91-3
