Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1) (Compiled from sources)

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
