Double proxy models are, as has been noted before, a questionable design
decision, but they should still work (the reason here: we need more than
one Admin interface for the parent proxy class). We have, basically, this:
{{{
class A(models.Model):
pass

class B(A):
class Meta:
proxy=True

class F(models.Model):
b = models.ForeignKey(B, related_name="bffs")

class C(B):
class Meta:
proxy=True
}}}

and when we try
{{{
qset = C.objects.filter(bffs__in=whatever)
}}}
we get "bffs not recognized, options are ..."

Not sure if this still happens with master, will try to repro later.
