Related to the last comment, about the testbed docs. Default here should be `DEBUG`, instead of `False`. Original line here was:
`TEMPLATE_DEBUG = hasattr(local_settings, "TEMPLATE_DEBUG") and local_settings.TEMPLATE_DEBUG or DEBUG`
(which had its own issues, now that I look at it, e.g. if `local_settings.TEMPLATE_DEBUG` were `False` but DEBUG were `True`)
