Thanks for the catch.  I have a feeling you'll run into this particular
bug a lot, as unregistering ucf-registered conffiles in postrm is almost
certainly a common thing.  I'll rework our postrm to use ucf iff it's
installed, and fall back gracefully to just manually deleting the
conffiles if it's not.
