Bug 311109

Application: ktorrent (4.1.3)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-34-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I use kdm on kubuntu 12.04
very often (but not always) I can't login on kde environment despite many reboot; i need to switch to a different environment. The safer is enlightenment.
Anyway, when i can't login, and so I use another window manager, I can't start ANY kde program. Most of them crashes at lauch.
I'm going crazy...

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
