Thanks,
Comment 1 Sebastien Bacher 2008-09-23 16:32:33 UTC 
the bug has already several duplicates on launchpad and is trivial to trigger by using the applet context menu to empty the trash for example
Comment 2 Sebastien Bacher 2008-09-23 16:44:46 UTC 
it seems to crash on "g_object_unref (applet->icon);"
Comment 3 Pedro Villavicencio 2008-09-23 16:47:25 UTC 
it also seems to happen only on amd64 platform we still don't have an i386 crash there.
Comment 4 Sebastien Bacher 2008-09-23 17:20:54 UTC 
the crash is easy to trigger on i386 too, just try to dnd something to the trash icon and empty it several times and you should get it, valgrind lists invalid read, it seems the applet->icon is freed before being used somewhere
Comment 5 Callum McKenzie 2008-09-24 01:18:17 UTC 
I can duplicate this and can also confirm that the fix suggested in bug 552577 fixes the problem. Applied to both gnome-2-24 and trunk.
