Google App Engine Helper for Django r52—the one that works with the Django 0.96 that comes stock with Google App Engine—no longer works with Google App Engine 1.1.8. It gives an error like:

cd mysite; /usr/bin/python manage.py runserver
Traceback (most recent call last):

The solution is to apply the patch from revision 68 (on Github) to your copy of google app engine for django helper.
