Application: ksysguard (4.8.3 (4.8.3))
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I was logged into an XFCE 4 session with KDE compatibility enabled. I ran the KDE System monitor which worked perfectly. However, when I closed the system monitor window, the crash notification/reporting assistant came up.
I'm running Kubuntu 12.04 (but was in an XFCE 4 session).

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