Jonas Fonseca b61d8d06d9 Fix crashes with various bogus BitTorrent URLs
... mainly bittorrent:// and bittorrent://x

The BitTorrent URL is supposed to contain an embedded URL pointing to a
metainfo file. If this is not the case a "custom" error message will be
shown. Also fixes calling of free_list() on an uninitialized list.

Closes bug 729.
