Thanks for the clarification. Brain is a bit slow this week.

The only way I can think that you may trigger this error during unpickling is if you have somehow managed to get an __implemented__ attribute on the object itself. Not sure how you would manage that.

Me neither!

Probably the best bet is to truncate your filestorage to a transaction before the change was persisted. Otherwise, you'll need to provide some more information, i.e. the pickle and the class definition. PDBDebugMode may be of help.

Only test data, fortunately.
