Application that crashed: ksysguard
Version of the application: 4.3.3 (KDE 4.3.3) "release 1"
KDE Version: 4.3.3 (KDE 4.3.3) "release 1"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
Just try it yourself. Right click on network, properties, sensors, double-click to change color, ok, apply, crash. It seems quite reproducible. KDE 4.3.3
