Bug 450811

Application: ktorrent (21.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.16.11-051611-lowlatency x86_64
Windowing System: X11
Distribution: Ubuntu 21.10
DrKonqi: 5.24.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I was waiting for the file to finish downlading.

ktorrent sometimes crashes when the dowload speed is very high and saturates my Internet access (1Gb/s).
I have never seen it crash when the download speed is limited by peers and is below my ISP limit.

The crash can be reproduced sometimes.

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