The following code raises an exception in Storm 0.17. It works as expected in 0.16
>>> from storm.locals import *
>>> database = create_database("sqlite:")
>>> store = Store(database)
>>>
>>> class Foo(object):
... __storm_table__ = 'foo'
... id = Int(primary=1)
... bar_id = Int()
...
>>> class Bar(object):
... __storm_table__ = 'bar'
... id = Int(primary=1)
... foos = ReferenceSet(id, Foo.id, order_by = Desc(Foo.id))
..
>>> bar = store.add(Bar())
>>> bar.foos
