Bug 245863

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
plasma-desktop is sometimes crashing when opening an application (eg: amarok)
or just by clicking onto a systray icon (eg: gtk networkmanager applet)
(currently using xBar )
isn't real trouble at all: plasma-desktop restarts immediately and everything's as before

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Plasma-Arbeitsfläche (kdeinit4), signal: Aborted
