Bug 237694

Application that crashed: ksysguard
Version of the application: 4.3.5 (KDE 4.3.5) "release 0"
KDE Version: 4.3.5 (KDE 4.3.5) "release 0"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.2-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
In the system load tab of System monitor when i try to change the background of the Network history to black the app crashes. The other graphes can be changed without chrashing.

 -- Backtrace:
