Hello,

the bug I'd like to report is a rather rare issue. It seems that on this particular torrent, ktorrent goes into a loop of infinite downloading (the program's working perfectly fine though) because some data of a particular piece, the final one it has left to complete, is corrupted.

My, rather limited as I have not studied Ktorrent's code in any detail, understanding of this seems to suggest that Ktorrent downloads corrupted data over and over again from the peers who keep sending it, causing some part of that piece to be corrupted all the time.

If you could point me at the particular pieces of code that may be relevant, I might be able to come up with a fix, if I can get Ktorrent to somehow identify which peers are sending the corrupted data and block them.

P.S.:Thank you for your time. I apologize if this bug is already fixed in a newer version, this particular version happens to be what Kubuntu uses and I have not yet recompiled KTorrent from source.

KTorrent should block the peer automaticly, why this isn't the case is a question to me.

Does that feature require any specific plugin? I may not have it activated automatically, causing the problem I had.

No this is a standard feature of KTorrent

I'll check SVN to see when it was added.

Hmm, doesn't seem to be in the latest changelog, so it's definitely in 2.2.1 indeed... Or at least, it seems to be.

So, the problem seems to be that somehow it doesn't kick in in this one specific case..

Bad peers can quite easily avoid detection

Ok, thanks, I'll chalk it up to some misbehaving other clients then.
