Application that crashed: ktorrent
Version of the application: 3.2.4
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I've downloaded the .torrent to the folder where I keep .torrent files (I have an option that ktorrent starts download automatially if new .torrent file found in this folder). Then I've selected the download location. And after that ktorrent crashed.
