i18n template tag loading error when setting 'show_indexes' to True

[MikiSoft]

This is a bug related to the django.views.static.serve and it's reproduced very easily.
First, create a new Django project and add these constants in settings.py:

STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'static/')

Then, in urls.py add this code:

from django.conf import settings
from django.views.static import serve
if settings.DEBUG:
    urlpatterns += url(r'^'+settings.STATIC_URL[1:]+'(?P<path>.*)$', serve, {'document_root': settings.STATIC_ROOT, 'show_indexes': True})]

Then create static folder in the project root make a directory and pu some file(s) in it.
The last step will be to start the server and to go to that directory (e.g. ​http://127.0.0.1/static), where response should be a directory listing of that folder, but you'll see this odd error:
'i18n' is not a registered tag library.
