Comment:

 __dict__ is entirely accessible on mapped objects.   You will have poor
 results if you populate it since you're bypassing the attribute tracking
 logic but it wouldn't produce anything like the above.

 Please attach a fully reproducing test case to this ticket to illustrate
 what specifically causes the issue else we'll have to close this ticket.
