Bug 195028

Application that crashed: khelpcenter
Version of the application: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-12-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I started khelpcenter (from network monitoring widget settings) and it crashed before showing the window itself. It doesn't happen every time, so I don't know how to reproduce.

 -- Backtrace:
Application: KDE hjelpesenter (khelpcenter), signal: Segmentation fault
