While trying to upgrade to v6 of this library we stumbled onto what we think is a bug.
When trying to
deepcopy
, orpickle
an model instance that:None
Then the
__getstate__
implementation will break since the descriptor doesn't include the variations.This was broken since #265, and released in 5.3.3 (I think).
I understand if this would be not seen as a bug, or not being merged because this library is unmaintained, then we would probably fork it and use the fork until we fully migrated.
