The m2m-refactor patch breaks ManyToManyFields on abstract models:
"AssertionError: ForeignKey cannot define a relation with abstract
class A"
{{{
class R(models.Model): pass
class A(models.Model):
r_set = models.ManyToManyField(R, related_name="%(class)s_set")
class Meta:
abstract = True
class B(A): pass
class C(A): pass
}}}
Disabling `create_many_to_many_intermediary_model()` if
`cls._meta.abstract` fixed it for me.
