[Comment from a bug report cleaner]
The crash seems to be related to the SystemMonitor engine. 
- Can the crash be reproduced if you temporary remove all your system monitor widgets from your Plasma setup ?
- If you run KSysGuard, does it also crash when disabling compositing ?
Regards

I removed the cpu monitor widget and haven't been able to reproduce it or crash ksysguard since.

Seems very similar to 241682 to me.
