Application that crashed: ksysguard
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
system monitor crashes on opening...no apparent reason, not immediately reproducable, next time it opened flawlessly. System was under load if that matters.

 -- Backtrace:
