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 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Changing the colours of the grid of the network pane in Ksysguard leads to crash.
It crashes when applying changes or pressing "OK" button.
It does not appen for the CPU and the Memory panes.
