Comment (by claudep):
Many thanks for the sample project which indeed triggers this bug.
The problem is that there are still leftover references of
'somemodel.account' foreign key on the `Account` model state (in
`_meta.related_objects`) even after it has been deleted. I think the
delete/remove operations do not clean enough metadata on related models.
Investigation continues...
