South an ImageField in Django

Question

South is a great thing for managing database fields but i don't understand - why on earth it doesn't work with ImageFields?

Here is my situation - i went through official South tutorial like this - my model:

from django.db import models


class Knight(models.Model):
    name = models.CharField(max_length=100)
    of_the_round_table = models.BooleanField()
    dances_whenever_able = models.BooleanField()

schemamigration Knights --auto and migrate Knights did well. But then i'm adding a field:

photo_of_a_knight = models.ImageField(upload_to='/photos/')

schemamigration --auto and migrate Knights result in a following error:

table "_south_new_Knights_knight" already exists

I saw some workarounds here but they are not useful for me. Finally i need to delete all tables related to South and my app and migrations will be done well. How do i overcome this?
