Bug 217655

Application that crashed: ktorrent
Version of the application: 3.2.5
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.6-145.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

What I was doing when the application crashed:
Started the ktorrent and I get segfault after couple minutes.
It keeps repeating after I restarted the program.
