-- Information about the crash:
Hi, I seem to be getting the same kind of crashes as when I reported bug #235287 (which was marked as a duplicate of bug #223243). KTorrent crashes simply while sitting in the background seeding, and the backtrace hints at uncaught exceptions (if I'm reading it correctly). This happens multiple times a day.

The crash can be reproduced some of the time.

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