So if the ultimate error message isn't entirely helpful, the traceback can
often help...

'page_not_found' sounds like a clue that the response Django is trying to
generate is an HTTP 404 Page Not Found. To confirm take a brief look at the
code identified in the detail:
http://code.djangoproject.com/browser/django/trunk/django/views/defaults.py#L69
and you can see it's probably 404.html that Django is trying to render.

Agreed the error message seems like it could be more helpful and identify
the template file that is trying to extend the non-existent file. If you're
sufficiently motivated and have the time, etc. you could try for a patch and
submit it.
The raw traceback instead of the Django debug page may be due to this
ticket:
