-- Information about the crash:
When I downloaded a torrent from internal browser, ktorrent crashed. It was right after I downloaded _and_ opened the torrent. There seems to be no problem with the torrent, after I restarted ktorrent, it started to download.

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