Application that crashed: ksysguard
Version of the application: 4.3.5 (KDE 4.3.5)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
systemmonitor crashed after changing propertiues of network traffic history graph.

How to reproduce:
1 - Run system monitor;
2 - Select tab "Carga do Sistema" (probably "System Load" in english);
3 - Right click on the "Network History" graph;
4 - Click on "Properties" on the popup menu;
5 - Click on the dialog button "Apply";
6 - Crash!

This above steps caused a crash every time I tried it.
