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: 4.5.3
Operating System: Linux 2.6.31.5-127.fc12.i686.PAE i686

What I was doing when the application crashed:
I just right clicked on the network graph in System Monitor to change the graph to detect my mobile gprs connection as a network and show its graph. The graph showed a single straight line, while I had a good internet connection. On right click I did not find any such option and no settings were changed, but instead the system monitor application just crashed.
