-- Information about the crash:
I keep the program open most of the time to check on resource consumption and insight into the system's operation. It crashes periodically. Don't really know why it does. 

The crash can be reproduced every time.

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