Bug 261935

Application: ksysguard (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- I was changing my partition with mdadm and lvm, was mounting new lvm partitions and was still reboot (maybe, it's the prbm, partitions table not yet reload?)
- amarok, dolphin, ktorrent, konsole, chromium were running. Plasma.

The crash can be reproduced every time.

-- Backtrace:
Application: Surveillance du système (ksysguard), signal: Segmentation fault
