 Given the models

 {{{
 from django.db import models

 class A(models.Model):
 pass

 class B(A):
pass

 class C(A):
pass
 }}}

 The query:
 {{{
 >>> A.objects.filter(b__isnull=False)
 }}}

 Generates bad SQL (specifically it omits the needed join).  Worth noting
 that:
 {{{
 >>> A.objects.exclude(b=None)
 }}}

 works correctly.
