I confirm this bug. I can confirm that 0.5.7.1~debian-1 (the only other available version in the debian pool) has the same bug.
The only version working correctly is 0.5.8-1. I had to download it from snapshot.debian.org: http://snapshot.debian.net/archive/2008/01/05/debian/pool/main/d/deluge-torrent/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
