Description

For a model defined similar to:

class MyModel(models.Model):
    mpoly = models.MultiPolygonField()
  
    objects = models.GeoManager()

trying to access mpoly as a deferred field leads to recursion error:

inst = MyModel.objects.get(id=1).mpoly  #works

inst = MyModel.objects.defer('mpoly').get(id=1).mpoly  #fails
RuntimeError: maximum recursion depth exceeded while calling a Python object

I cannot repoduce this error on 1.5 or master. It would be nice if you could create a failing test case in the GeoDjango test suite.
