Hi Michael,
I see now that most of the Django tests that are still failing seem to be
forward referencing problems. Django inserts a record to a table with a
reference to something that doesn't exists (yet). I find it a bit hard to
debug, since I've not managed to disable transactions while running the
tests (setting autocommit in the settings file as no effect) and thus can
not query the database.
Here is one stacktrace:
"""
