Comment (by mrmachine):
I think I've finally cracked it. When working with model instances that
have deferred fields, you need to call `get_fields_with_model()` on the
original model to get non-local fields correctly. You can access the opts
for the original model with `rel_obj._meta.proxy_for_model._opts`. I have
just updated the patch. The full test suite passes, so I think this is RFC
now, but I will wait for review by more a set of eyes more experienced
with the ORM.
