This following request works fine and produce the result I was
expecting session.query(UserRss, Rss, Item).join([Rss, Item]). But
count doesn't work. Is it a bug, or did I miss something ?
>>> str(session.query(UserRss, Rss, Item).join([Rss, Item]).count())
Traceback (most recent call last):
File "<console>", line 1, in <module>

sql.func.count,
nested_cols=list(self._only_mapper_zero().primary_key))

Thanks.
