Without more information about what you were trying to do, what your model setup is, what your settings are, etc., it's impossible to tell if this is a configuration error or an actual bug. Your best bet is to post details to the Django users mailing list (​http://groups.google.com/group/django-users/) or in the Django IRC channel (#django on irc.freenode.net) and ask for help tracing the source of the problem.
