ImportError: cannot import name _args_from_interpreter_flags

I have a flask app which uses multiprocessing when computing stuff. When I add import flask.ext.testing at the top of my test module (and nothing else, not using it yet), I get this when I run my tests:

Traceback (most recent call last):

Twill has a own subprocess implementation which breaks some things. See issue #36.

bump, Does anyone have a workaround for this?

This fixes the issue for me:

pip install Flask-Testing --upgrade
pip uninstall twill
