Comment (by ramiro <rm0 _at_ gmx.net>):
Find attached a {{{models.py}}} file that contains six model pairs with
mutually referential many-to-one relationships. Every pair of models
modifies something trying to isolate the real cause. Conclusion: it seems
problem is related to the fact the FK name is equal to the related model
name but in lowercase (something already hinted by bmurdock in a comment
above).
Note that the doctest in the Child model creates a
{{{Child.AddManipulator}}} instance w/o getting any error but the
same instantiation leads to the reported traceback when the user is going
to create a {{{Child}}} instance in the Admin app.
