When I include a ModelToModelField to one of my models the following error is thrown.

Traceback (most recent call last):

_mysql_exceptions.OperationalError: (1050, "Table 'orders_proof_approved_associations' already exists")

Field definition:

approved_associations = models.ManyToManyField(Association)

Everything works fine when I remove the field, and the table is no where in site.

Any thoughts as to why this would happen?
