Description (last modified by Ramiro Morales)

Models with GenericRelation fields defined as:

the_relation = generic.GenericRelation('Related')

produce objects that cannot be deleted:

>>> obj.delete()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "lib/django/db/models/", line 463, in delete
  File "lib/django/db/models/", line 867, in delete_objects
  File "lib/django/db/models/sql/", line 61, in delete_batch_related
    field =
AttributeError: 'str' object has no attribute '_meta'

I'm pretty sure the bug here is that generic relations aren't correctly accepting strings and need an actual class.
