16861	Fixtures do not work with namespaced apps	jlsherrill@…	nobody	"
If you have an app that is ""foo.bar"" instead of just ""foo"" it seems as if it is impossible to create fixtures for them.  For example the app  django-allauth  includes multiples apps within it:

* allauth.facebook
* allauth.twitter
* etc..

You can use it just fine, but if you try to use a fixture, for example:
{{{
- model: allauth.facebook.models.FacebookApp     #  (same error with allauth.facebook.FacebookApp)
  pk: 1
  fields:
    name: TestApp
    site: ""1""
    application_id: 1234
    api_key: Foo
    application_secret: FOOO
}}}

importing will fail with this traceback:

{{{

}}}
It seems that the get_model() call within _get_model() of /django/core/serializers/python.py is splitting the 'model' from the fixture which doesn't seem correct.

Affected code (/django/core/serializers/python.py)
{{{
