Hi all!
I'm running SQLAlchemy 0.6b2 for a while and i've seem some strange
exception (AttributeError: 'NoneType' object has no attribute
'_sa_iterator') happening one in a while.
This is my stacktrace:
Traceback (most recent call last):

line 570, in __iter__
return iter(getattr(self._data(), '_sa_iterator')())
AttributeError: 'NoneType' object has no attribute '_sa_iterator'
I don't have a good test for this, but i'm trying to create one.
Does anyone knows why this is happening?
Thanks!
