If i try to open a created url i get an 500 error.

My procedure was:

First python manage.py startapp black

I added in project/settings.py under INSTALLED_APPS 'black',

I added in project/urls.py url(r'^test/', include('black.urls')),

Content of black/urls.py is:

from django.conf.urls import patterns, url
from black import views

urlpatterns = patterns('',
url(r'^$', views.index, name='index')
)

And content of black/views.py:

from django.http import HttpResponse

def index(request):
        return HttpResponse("SHOW ME: BLACK")

After all i synced the database.

I can't see any error in apache-error-log and also not in my posted django files. What could cause this?
