[Comment from a bug triager]
Indeed, this looks like bug 237954 (which seems to be a Qt bug)
- What is the "system monitor" you are using ? Did you download/install it from the Internet or other third-party places ?
- If you can repeat this crash again, it could be useful to test it with an updated Qt version to check if their bug is fixed now.
Regards

Comment 2 Rafal Jezewski 2011-04-06 09:01:22 UTC

System monitor (plsma widget) is from standard instalation from gentoo package system.  

I updated Qt (4.7.1) and KDE (4.5.5) and bug gone away. So I can't confirm that updating only Qt fix issue.
