Hi,
I've started seeing errors like this:
------

Traceback (innermost last):

AttributeError: 'None' object has no attribute 'load'
...popping up from time to time. I think they're coming from a product we've
written, but beyond that I have no idea what's going on.
I hazard a guess that you're changing a mutable attribute of a persistent object, without doing a _p_changed=1 on your persistent object.
