Select related() not working as of Beta

[Yeago]

Given the following expression:

bmodels.Contact.objects.select_related('IR_contact','consumer_contact','program','consumer').filter(consumer__file=file).order_by('-date')

And the following models:

class Contact(models.Model):
    program = models.ForeignKey('agency.Program')
    consumer = models.ForeignKey('consumer.Consumer',null=True,blank=True)
    date = models.DateField('Contact Date')
    notes = models.TextField()
    date_added = models.DateTimeField(editable=False)
    method = models.CharField(max_length=10,choices=choices.CONTACT_METHOD,\
            null=True,blank=True)

# consumer_contact
class Contact(basemodels.Contact):
    base = models.OneToOneField(basemodels.Contact, parent_link=True,related_name="consumer_contact")
    service = models.ForeignKey(Service)
    confidential = models.BooleanField(default=False,help_text='These notes will not be visible to general staff')
    group = models.ForeignKey(Group,null=True,blank=True)
    group_contact = models.ForeignKey('consumer.GroupContact',blank=True,null=True)

    def save(self, *args, **kwargs):
        super(Contact, self).save(*args,**kwargs)

    class Meta:
        permissions = (
            ("allow_confidential", "Can make contacts confidential"),
        )

#ir_contact
class Contact(basemodels.Contact):
    base=models.OneToOneField(BaseContact,parent_link=True,related_name='IR_contact')
    IR=models.ForeignKey(IR,blank=True,null=True)
    referred_from=models.ForeignKey(ReferralSource,related_name='IR_referred_from')
    referred_to=models.ManyToManyField(ReferralSource,related_name='IR_referred_to')
    information=models.ManyToManyField(Information,verbose_name='Information Requested') 

the following SQL is produced:

SELECT (fields) FROM `base_contact`

LEFT OUTER JOIN `consumer_consumer` ON (`base_contact`.`consumer_id` =
`consumer_consumer`.`id`) # ok

INNER JOIN `agency_program` ON (`base_contact`.`program_id` =
`agency_program`.`id`) # ok

LEFT OUTER JOIN `consumer_contact` ON (`base_contact`.`id` =
`consumer_contact`.`base_id`) # ok

INNER JOIN `base_contact` T5 ON (`consumer_contact`.`base_id` = T5.`id`) # ?!?

# These next two are questionable, since they are joined on a LEFT
OUTER (so they may potentially not be there)

INNER JOIN `consumer_service` ON (`consumer_contact`.`service_id` =
`consumer_service`.`id`)

INNER JOIN `consumer_servicetype` ON (`consumer_service`.`type_id` =
`consumer_servicetype`.`id`)

LEFT OUTER JOIN `IR_contact` ON (`base_contact`.`id` =
`IR_contact`.`base_id`)  # ok

INNER JOIN `base_contact` T9 ON (`IR_contact`.`base_id` = T9.`id`) # ?!?

WHERE `consumer_consumer`.`file` = 06-1757 ORDER BY `base_contact`.`date` DESC 

As you can see, there are two INNER JOINs which are messing up this otherwise valid and expected query.
