Similar to bug #189497, an incompatibility based on a change in twisted.web.client is needed to deluge. It has apparently been committed to deluge 1.3-stable, and will be in 1.3.12. It looks like 1.3.12 isn't out yet, but pre-applying this patch to the FreeBSD port would be helpful to me at the moment. http://dev.deluge-torrent.org/changeset/d40dfcd53c243 Thanks.
I should also note the deluge ticket from where I acquired that link to the change for 1.3-stable: http://dev.deluge-torrent.org/ticket/2737
