Application that crashed: konqueror
Version of the application: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was using in root-mode. Dolphin just crashed after clicking on a folder.

Before that I was able to compress a folder to a zip-file and move the zip-file into the folder. While trying to look into the folder dolphin died away - leaving a backtrace.

 -- Backtrace:
