Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.86 (KDE 4.2.86 (KDE 4.3 >= 20090514)) "release 125"
Qt Version: 4.5.1
Operating System: Linux 2.6.27.21-0.1-default i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
Plasma chrashed directly after booting (I didn't start any programm manually and my autostart just started knetworkmanager and qt-engine scrypt). While I wrote this report, Plasma chrashed a second time. 
Some days ago I had the same bug.
