Bug 220497

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.x86_64 x86_64

What I was doing when the application crashed:
I was trying to change to orange the colour of the pale yellow Receiving line in the Network History part of the default System Load tab.  When I clicked Apply, System Monitor crashed.  I can consistently reproduce this by repeating these steps.

 -- Backtrace:
Application: System Monitor (ksysguard), signal: Segmentation fault
