-- Information about the crash:
The onlyu pattern I noticed is that it happens whan there are multiple (>1) downloads, but beside that no clear indication.

When the problem starts, it keep happening after few minutes (sometime after <1 minute) and I have to keep re-opening it until I can finally finish the download and remove the items.

When there is no torrent in the application, the problem doesn't happen.

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
