21132	AdminSite cannot handle different namespace	Markus Holtermann	Tim Graham	"Assume you have a custom admin inheriting from django.contrib.admin.sites.AdminSite and you want to run it with its own namespace:

{{{
# testproject/urls.py 
from django.conf.urls import patterns, include, url
from django.contrib.admin.sites import AdminSite

my_admin = AdminSite(name='name', app_name='app_name')

urlpatterns = patterns('',
    url(r'^admin/', include(my_admin.urls)),
)
}}}

This is going to fail with the following error:

{{{
