Run it with Deferred.debug set to True. That'll give you more
information about the source of the error. You might need to work with
an unfrozen version here—I don't know for sure though.

For what it's worth, "Unhandled Error" means that a Deferred has
failed somewhere in its chain and there is no errback to handle that
failure.
