-- Information about the crash:
- What I was doing when the application crashed:
Dwonloading in K Torrent and the first time it crashed I was trying to access files already downloaded but now seems to be happening if I access another program. In the last case I accessed firefox.

The crash can be reproduced some of the time.

-- Backtrace:
