Bug 270021

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1) "release 2"
Qt Version: 4.7.2
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I was listening to music in Amarok and I did some settings in Amaroks settings: I switched off (ticked off) "show icon in taskbar" in Amarok and as soon as I hit "apply" Plasma crashed and restored immediatly. This can not be repeated anymore.

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