Installed from:    Compiled sources

Just back from dining :) after unlocking my workstation I got this plasma crash report (although plasma already automagically restarted itself so everything was working again)

Comment 1 Aaron J. Seigo 2008-12-23 20:16:22 UTC 
by "unlock" you mean unlock the screensaver only? e.g. you weren't also unsuspending/unhibernating the computer?
Comment 2 Davide Ferrari 2008-12-23 20:23:01 UTC 
Exactly, just unlocking the screensaver, no hibernate/sleeping/whatever at all.
I'm using KDE4.2beta2 (Kubuntu packages) btw
Kmail/Kopete opened in background so they were generating notifications
Comment 3 Davide Ferrari 2008-12-24 17:30:22 UTC 
Just got another similiar crash. This time I was logged in and working, plasma "freezed" (I mean, for example I was changing virtual desktop and the taskbar wasn't reflecting the change), then  a notification from kmail arrived, plasma just drawn a black square (no svg/text painted at all) where notifications appear usaully, and then it crashed with this backtrace
