Bug 225832

Application that crashed: ksysguard
Version of the application: 4.3.4 (KDE 4.3.4)
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-7.slh.7-sidux-686 i686

What I was doing when the application crashed:
When I filter the list of processes in ksysguard (quick search) and then start kontact ksysguard crashes. It happens when I use the filter term "kon" on the tree to view akonadi processes and then start kontact. But it also happens when I use a filter like "wri" which has nothing in common with "kontact". As soon as kontact starts ksysguard crashes. Ksysguard does not crash when I start Kontact when no filter is set in ksysguard. Ksysguard does not crash when I e.g. start kwrite while a filter is active.
