Description Matthias 2012-01-31 14:51:04 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.00 (4.8.0 (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.2.1-gentoo-r2-Saberhagen x86_64
Distribution: "Gentoo Base System release 2.0.3"

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

Started/closed programs/used chromium/...

- Unusual behavior I noticed:

After the startup the taskbar randomly freezes for some seconds/minutes and working again. This happened many times a day until the complete taskbar/widget crashed and stopped working.

- Custom settings of the application:

KDE 4.8.00 with standard settings

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Aborted
