-- Information about the crash:
Loaded plugins: infowidget, zeroconf

KTorrent crashed right after I kicked some peers on the "Peers" tab from the infowidget. They shared the same IP address with other peers (most of them had a score of -50 and none of them downloaded anything).

 -- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
The current source language is "auto; currently asm".
