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 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I used the default configuration of systemmonitor.
In the first two graphs (CPU nad Memory) I can change the settings just fine. If I try to do this on the third graph (Network) systemmonitor crashes reliably.

 -- Backtrace:
Application: Systemmonitor (kdeinit4), signal: Segmentation fault
