OneToOneField being ignored in Django Admin

[andrew_rust@…]

I have the following models set up:

---

from django.db import models
import datetime

class Ref(models.Model):
    ref = models.CharField(max_length=200)

    def __unicode__(self):
        return self.ref

class Poll(models.Model):
    ref = models.OneToOneField(Ref, verbose_name='reference')
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

    def __unicode__(self):
        return self.ref

    def __unicode__(self):
        return self.question

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice = models.CharField(max_length=200)

    def __unicode__(self):
        return self.choice

class Vote(models.Model):
    site = models.CharField(max_length=200)
    choice = models.ForeignKey(Choice)
    votes = models.IntegerField()
    date = models.DateTimeField('date voted')

    def __unicode__(self):
        return self.site

from django.contrib import admin

class ChoiceInline(admin.TabularInline):
    model = Choice
    extra = 5

class PollAdmin(admin.ModelAdmin):
    fieldsets = [
        ('Poll Information', {
                'fields': ('ref', 'question')
        }),
        ('Date information', {
                'fields': ['pub_date']
        }),
    ]
    inlines = [ChoiceInline]
    list_display = ('question', 'ref', 'pub_date')
    list_display_links = ('question', 'ref')
    list_per_page = 25
    search_fields = ['question']
    save_on_top = True

admin.site.register(Poll, PollAdmin)

When trying to run syncdb against this i get the following error....

If i change the OneToOneField to a ForeignKeyField then syncdb runs with no problems.
