Description Marko Hänninen 2011-03-19 12:38:38 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38 x86_64
Distribution (Platform): Gentoo Packages

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

My system was under high load (compiling OpenOffice), so I closed Amarok and Kontact. Right after this Plasma crashed. I have seen similar crash before under high system load.

The crash can be reproduced some of the time.

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

New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.6.1 (4.6.1) using Qt 4.7.2

- What I was doing when the application crashed:
During a heavy update (zypper up) the system was under high load. I decide to close amarok. Then immediately the crash occurs. 
Plasma restart by itself.
