Using get_or_create in a view

I am importing users from LDAP into MySQL and I want to get/create profiles as such:

profile_obj, created_profile = UserProfile.objects.get_or_create(user=user_obj)

Django's throwing me an exception, which seems completely ironic considering the function I am using.

UserProfile matching query does not exist.

Am I using it incorrectly?

Edit:

As per a request below, the save function.

def save(self, force_insert=False, force_update=False, using=settings.DATABASES['default']):

    super(UserProfile, self).save() # I just added this line and it seems to work now.

    this = UserProfile.objects.get(id=self.id)

        THUMB_SIZE = (50, 50)

        #self.thumbnail = self.photo

        image = Image.open(self.photo.path)

        if image.mode not in ('L', 'RGB'):
            image = image.convert('RGB')

        image.thumbnail(THUMB_SIZE, Image.ANTIALIAS)
        (head, tail) = os.path.split(self.photo.path)

        image.save(head + '/thumbs/' + tail)开发者_运维知识库

        self.thumbnail = a + '/thumbs/' + b

    super(UserProfile, self).save()
