"Add URL" complains that valid torrent URLs aren't valid

[pcj]

When trying to add torrents from nyaa.se by URL, µTorrent 1.9.1 (30063) complains that the URL is not valid and refuses to add it.  An example URL: http://www.nyaa.se/?page=download&tid=526155

 

If I modify the URL to include "&.torrent" on the end of the URL, then it takes it, so obviously it's just looking for .torrent on the end of the URL, but that's an annoying extra step (and thankfully nyaa ignores that in the URL and still gives you the file).
