Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) "release 197"
Qt Version: 4.6.0
Operating System: Linux 2.6.27.39-0.2-pae i686
Distribution: "openSUSE 11.1 (i586)"

-- Information about the crash:
Prior to the crash, an application (which was grouped in the taskbar) was closed, but this didn't seem to be a problem (I'm writing this because I read that this was a problem in another bug report). Then I wanted to switch tasks (ALT + TAB) and thereupon Plasma crashed.

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