What I was doing when the application crashed:
Had ksysguard running with tab open to monitor cpu, memory & network, left it running for several hours all ok, then it just crashed out and have not been able to use it since, ive tried installing all the -debug packages that i thought might be required but still not getting a proper backtrace, i also had virtualbox running, also had net-applet running with monitor network

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