Bug 208712

Application that crashed: ksysguard
Version of the application: 4.3.1 (KDE 4.3.1)
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Launching system guard from lancelot or kickoff causes the system monitor window to show momentarily and then crash. It opens to the tab with network, cpu, and memory graphs. It seems to crash after the first refresh of the graphs.
However, when lauching System Guard from krunner, it does not crash. The difference is that the System Guard lauched by Krunner does not have a tab for the cpu/network/memory graphs.

 -- Backtrace:
Application: System Monitor (kdeinit4), signal: Segmentation fault
