Bug 303008

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed: just move cpu/ram/net monitor to a different place. This happened 2 times in a row. The third time it worked without error

The crash can be reproduced some of the time.

-- Backtrace:
Application: Powłoka pulpitu Plazmy (plasma-desktop), signal: Segmentation fault
