Application that crashed: ktorrent
Version of the application: 3.2.4
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Ktorrent stopped a torrent like 10 minutes before it crashed and said there was too many files opened. Maybe because the torrent had more than 20000 seeders and 40000 leechers ? Then it crashed when it was in the background, I haven't done anything to disturb it. Crashed and said 'segmentation fault'

 -- Backtrace:
