Alessio Bogon:

I attach a patch for the test_mapper.py module that reproduces the issue.
To sum it up, if you query an object without any options and then you query it again but using options like `joinedload`, these are ignored, unless you do a session.expunge_all() or you delete the queried object from the local scope (by using `del` statement).
