Comment:

 Right, we've got a working test case:

 {{{
 class Parent(models.Model):
     name = models.CharField(max_length=10)
     other_value = models.IntegerField(unique=True)

     def __unicode__(self):
         return u"XXX: %s" % self.name

 class Child(Parent):
     father = models.OneToOneField(Parent, primary_key=True,
 to_field="other_value", parent_link=True)
     value = models.IntegerField()

     def __unicode__(self):
         return self.name
 }}}

 The bug looks to be related to the combination of `parent_link` and
 `to_field`; editing a `Child` in the admin will through transaction
 management errors intermittently.
