Comment (by lamby):

 FYI this was also affecting OneToOne fields, eg.:

 {{{
 class Parent(models.Model):
     pass

 class Child(models.Model):
     parent = models.OneToOneField(Parent, related_name='child')
     ordering = models.IntegerField()

     class Meta:
         ordering = ('ordering',)

 >>> Parent.objects.order_by('child')
 # (boom)
 }}}

 Calling:

 {{{
 >>> Parent.objects.order_by('child__ordering')
 }}}

 .. would temporarily "fix" it.

 Mentioning it in case you want to expand the release notes and for anyone
 else hit by this issue in 1.9.1
