While downloading from large and/or long-running torrents, it is quite often that after hours of downloading I check up on the status only to find all torrents are in the 'stalled' status and all activity halted. Restarting KTorrent immediately causes download to resume properly, so it's not a matter of external problems at that point, although it's possible that some intermittent problem occurs at some point and KTorrent does not recover from it properly (just guessing). In any case, if restarting KTorrent solves the problem (until the next time it happens), it means it's a bug in KTorrent.

Reproducible: Sometimes

Steps to Reproduce:
download from a couple of long-running torrents.

Actual Results:  
All torrents stalls and no activity until KTorrent is restarted.

Expected Results:  
KTorrent should continue downloading from the torrent until completion.

Currently I'm running KTorrent 4.0.5 on Kubuntu Natty with KDE 4.6.4 from the kubuntu ppa. The same issue existed in previous versions, e.g. KTorrent 4.0.3 on Maverick with KDE 4.6.3 and I think also 4.6.2. I don't know in what version exactly this bug was introduced.
