Recently I started having the error
"""An error occurred while loading the torrent. The torrent is probably corrupt or is not a torrent file."""
when trying to load a torrent by URL in ktorrent. If I download the file by hand and open it ktorrent loads it fine. I can attempt to trace the traffic but I'm controlling it remotely over a *very* slow link so I would rather not if there are easier things to try.

What is the link you are trying to access? It may be that they are doing things through PHP and that ktorrent isn't following the link.

Or it could be a website requiring a login.
