I was having similar problems. It consistently hung if I did a 'nosetests -f tests/test_controllers.py'
I figured it might be something with cherrypy hanging up, so I ran 'easy_install -U .' in the thirdparty/cherrypy directory, and that seemed to resolve it. It said I had 2.2beta installed, but I guess I got out of sync. Anyways, just another datapoint.
