Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

I did an ungroup of a group of about 5 windows. Then I can't say - I was using the windows (open-office) and also a mail was received (which I remember as my mail aarival sound played). That means, also the "new mail" icon of kmail appeared in the system tray)

-- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
