Django XML serializer does not namespace georss properly

What steps will reproduce the problem?
1. Create model class and save an instance to the datastore
2. Import serializers from django.core
3. Serialize <model>.all() queryset via serializers.serialize("xml",
<model>.all())

--Example--
from django.core import serializers
from appengine_django.models import BaseModel
from google.appengine.ext import db

class ExampleModel(BaseModel):
   name = db.StringProperty()
   age  = db.IntegerProperty()
   location = db.GeoPtProperty()

inst = ExampleModel(name='Some Guy', age=28, location=db.GeoPt(10,20))
inst.save()

myStr = serializers.serialize("xml", ExampleModel.all())
print myStr
objs = serializers.deserialize("xml", myStr)
objs.next()

Traceback (most recent call last):
  File "<console>", line 1, in <module>

line 38, in fatalError
    raise exception

What is the expected output? 
 * Successful serialization and deserialization of objects 
 * XML representation similar to below (note the xmlns declaration):

<?xml version="1.0" encoding="utf-8"?>
<django-objects version="1.0" xmlns:georss="http://www.georss.org/georss">
<entity kind="examplemodel"
key="ahdzdHJlZXR2aWV3Z2FkZ2V0YmFja2VuZHISCxIMRXhhbXBsZU1vZGVsGAgM">

  <property name="age" type="int">28</property>
  <property name="location" type="georss:point"><georss:point>20.0

  <property name="name" type="string">Some Guy</property>
</entity>
<entity kind="examplemodel"
key="ahdzdHJlZXR2aWV3Z2FkZ2V0YmFja2VuZHISCxIMRXhhbXBsZU1vZGVsGAkM">

  <property name="age" type="int">15</property>
  <property name="location" type="georss:point"><georss:point>22.0
33.0</georss:point></property>
  <property name="name" type="string">Some Kid</property>
</entity>
</django-objects>

What do you see instead?
SAXParseException: <unknown>:6:48: unbound prefix

XML representation lacks xmlns declaration for georss namespace.

What version of the product are you using? On what operating system?
App Engine SDK v1.1.0.1 - Mac OS X 10.5.3
