--- Comment #17 from Austin English austinenglish@gmail.com 2010-09-22 17:56:28 CDT --- uTorrent has a similar problem, not sure if it's related or not. I'm hesitant to file a bug though, until this one is fixed.
For uTorrent, it asks to be the default torrent handler on startup. Choose yes, close, restart. Guess what happens next? :-p
