I've simplified the save method to contain only the super call, and
the stack trace points at it
super(self.__class__, self).save(force_insert, force_update)
exclusively. That is, my test calls a Mymodel.objects.create() at line
1045, and then Mymodel.save is called that was defined in the abstract
model.
Traceback (most recent call last):

super(self.__class__, self).save(force_insert, force_update)
RuntimeError: maximum recursion depth exceeded
I have tried many variants, like moving the save method to the child
models without getting rid of the save method of the abstract model,
and with deleting it totally.
In the latter case there are no problems at all. In the former (when
the abstract model has a ``super(self.__class__, self).save
(force_insert, force_update)`` save method) the same recursion occurs.
any ideas?
