KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
It seems to have happened after I shutdown Ubuntu without closing the application. Afterwards, everytime I tried to open ktorrent it crashed.

The crash can be reproduced every time.
