I fixed this about two weeks ago in Rawhide; but keeping it built against an internal copy of libtorrent in Fedora 9/10 is a necessary evil at this point. Deluge *requires* the 0.14 series of libtorrent at minimum for its functionality. (In fact, I just tried it with a system copy of libtorrent .13 and it simply hangs on starting the daemon.) However, the upgrade from rb_libtorrent 0.13 to 0.14 changes the API/ABI and breaks backward-compatibility, so it is only in Rawhide at this time. In fact, Deluge in Rawhide *is* using the system copy of rb_libtorrent, so this is no longer an issue there. See: https://www.redhat.com/archives/fedora-devel-list/2009-January/msg00373.html It is that older Fedora releases are using such old versions of libtorrent which causes Deluge to require its own internal (far newer) copy. And upgrading those Fedora releases with the newer libtorrent is a definite no-go at this point in time, due to these compatibility-breaking changes. Apologies for any inconvenience this may cause! Thanks for the bug report; and please feel free to re-open this with more details if you have any further questions or comments, et al. :)
