Fixture problem with child models

[casey@…]

There seems to be a problem importing fixtures for child models. Supposing I have a model myapp.MyGroup that inherits from auth.Group, and I have a fixture that includes MyGroup data, I receive the following error:

psycopg2.ProgrammingError: column "id" does not exist at character 54

generated from this SQL:

SELECT setval('"myapp_mygroup_id_seq"', coalesce(max("id"), 1), max("id") IS NOT null) FROM "myapp_mygroup";

As far as I can tell, it appears that it is attempting to updating the sequence for the pk of the child model (for which there is none) using the "myapp.mygroup.id" column (which doesn't exist).
