Bug 320305

Application: ktorrent (4.3.1)
KDE Platform Version: 4.10.3 "release 563"
Qt Version: 4.8.4
Operating System: Linux 3.4.33-2.24-desktop x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I had started KTorrent half an hour ago or so. I wasn't interacting with it when it crashed. In fact, I was looking at a different virtual desktop than the one on which KTorrent runs.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
