I got the same crash and the backtrace. For me it happened when a contact in Kopete came online, and a notification of this even was shown briefly and then it crashed. SVN commit 1064330 by mart: since notification can die, put it behind a QWeakPointer BUG:219384 M +20 -18 notificationwidget.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1064330 Created attachment 39314 [details]

Version: (using Devel) OS: Linux Installed from: Compiled sources I was sitting here, watching a movie, IMing a friend, when plasma-desktop crashed. I can't remember if recieving a new message triggered this or not, but there definitely were some old notifications in the list. Poking around in the mess with gdb gets some interesting results: (gdb) frame 7 #7 0x06bea4c4 in NotificationWidgetPrivate::updateNotification (this=<value optimized out>) at
