Description
When a model class has a one-to-many relationship with itself, the get_relatedobject methods of the many-side classes will be overwritten by the method of the one-side's class.
Example:
class Test(meta.Model):
parent = meta.ForeignKey('self', blank=True, null=True)
Create two objects of that kind, set one to be the parent of the other, then try test.get_parent() on the child object. A UnitDoesNotExists exception will be raised.
Note:

Fixed on r2446.
