Application that crashed: ksysguard
Version of the application: 4.3.1 (KDE 4.3.1) "release 6"
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
The "System Monitor" (ksysguard) crashes when properties of the "Network History" graph are changed. The program crashes when the "Apply" or "OK" buttons of the "Properties" dialog are clicked; even when no values are really changed.   

To reproduce:
Go to "System Load" tab.
Right click on "Network History" graph.
Click on "Properties" menu entry.
Click on "Apply" or "OK" buttons of "Properties" dialog.
-> The program crashes.
