Bug 314779

Application: ksysguard (4.10.00)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.7.5-030705-generic x86_64
Distribution: Ubuntu 12.10

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

I startet ksysguard and typed 'chrome' in the filter text box. ksysguard crashed after a few seconds.

The crash does not seem to be reproducible.

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