Bug 230488

Application: ksysguard (4.4.67 (KDE 4.4.67 (KDE 4.5 >= 20100310)))
KDE Platform Version: 4.4.67 (KDE 4.4.67 (KDE 4.5 >= 20100310)) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.31.12-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
When starting KSysguard either directly, or via the KRunner system monitor, I get this crash after a short time, probably when the next list update should be done.

I switched to Qt 4.7 tp yesterday, and blamed a regression in Qt for the bug, but seeing there are duplicates even with Qt 4.5.x, I think the problem is in KSysguard, so before filing a bug to Nokia, I want to make sure where the bug is.

The crash can be reproduced every time.

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