Well seems like the project you want to access is just None. SA can't do
anything with it. I had a similar problem recently, it was bacause the
objects got garbage collected before being accessed. A testcase would be
really helpful.

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):

I don't have a good test for this, but i'm trying to create one.
Does anyone knows why this is happening?
Thanks!
