Comment:
This is not yet fixed for me. In my session data I have a list of models
created by MyModel.objects.create(). This was working fine with 1.1.1 and
gave me the error "PicklingError: Can't pickle <type 'function'>:
attribute lookup __builtin__.function failed" prior to changeset 12866.
Post fix, I'm now getting "TypeError: expected string or Unicode object,
NoneType found" at "pickled = pickle.dumps(session_dict,
pickle.HIGHEST_PROTOCOL)".
A workaround is to do MyModel.objects.get(pk=the_new_pk) immediately after
creation and storing this model object in the session.
