Give useful feedback to developer if a bad url is used for a static file

[Håkan Lövdahl]

in django/core/handlers/base.py there is a problem.
Sometimes when using the statichandler it throws an exception without any useful information.
I would like to propose an update the BaseHandler class

    def get_response(self, request):
        """Return an HttpResponse object for the given HttpRequest."""
        # Setup default url resolver for this thread
        set_urlconf(settings.ROOT_URLCONF)

        if self._middleware_chain is None:
            if self.__class__.__name__ == 'StaticFilesHandler':
                uri = '%s' % (request.get_full_path() )
                raise ValueError('Bad path for static file: %s' % uri)

This would help for keeping the test-outputs nice and clean.

What are the steps to reproduce the error?

And as far as the solution goes, putting a mention of StaticFilesHandler in BaseHandler doesn't look appropriate.
