This looks like a circular dependency error. The call to
Group.objects.get is at module level, so it is executed when the
module is first imported. Since you haven't run syncdb successfully
yet, at the point when that line is executed, the group table doesn't
exist.
I would suggest moving that call into a function, but it looks like
you're not using it at all, so I would leave it out.
