Bug 243881

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

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

The X server icon appears some time in the panel for no obvious reason.By clicking on close, it kills plasma.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma-Arbeitsfläche (plasma-desktop), signal: Aborted
