Could you post the entire content of your script? There is no way those 2 lines (and the necessary "os" import) can cause this error.

You are right. I investigated much deeper. Turns out this is what I did.

1. Script imported root URL conf

2. Through an URL include, many other URL confs were imported

3. Many URL confs import CBVs from views.py

4. These views.py may import models or import modules that import models

5. At some point a queryset was evaluated during an import

In this particular case, it was a choices field on a form. I have since changed this to use ModelMultipleChoiceField.

I guess I'll need to be really careful to not evaluate a queryset or stop using CBV (to avoid the imports). Seems a bit fragile.
