Application: ktorrent (4.0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

- running KTorrent 4.0.3 italian version
	- upload limit to 10.0 KiB/S
	- added pre-existent file, which download was not completed yet, to download
	- checked data and found uncorrect data (system freezed while checking)
	- continued downloading without checking data anymore, then started crashing
- other applications: just using a web browser (chromium) and running skype and kopete

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Bus error
