找不到Django管理模板

Question

Suddenly django admin couldn't find login template. When accessing /admin/ it raises TemplateDoesNotExist .

Strange thing is that it searches for admin/login.html.html that, obviously, does not exist in any of paths supplied.

Any idea where does it add the extra .html ?

EDIT:

url.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', include('dashboard.urls')),
)

Traceback:

Internal Server Error: /admin/

Core is the module that contains settings.py, urls.py and models.py (core models, that are project-wide)

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'core',
    'dashboard',
    'south',
)

Appears that coworkers had added middleware that should handle RESTful requests and messes with the template loader. So there was the problem.
