Django 1.9 Apps aren't loaded yet

I am developing a django app. I had the basic site running, but I had
not yet created any models. I created a model, and now the server
fails to start with "Apps aren't loaded yet"

traceback below. Anyone know what I am doing wrong?

Traceback (most recent call last):
