CELERYD_FORCE_EXECV causes crash on Ubuntu Oneiric

[mattlong]

Attempting to upgrade from django-celery 2.4.2 to 2.5.1. Setting CELERYD_FORCE_EXECV = True in my settings.py causes python manage.py celeryd to fail to start and infinitely loop an import error. I observed the same behavior in the demo project included with the django-celery source code. The stacktrace of the error that repeats indefinitely is shown here: http://pastebin.com/4WpQ14qd

To repro:
My environment consisted of a completely clean Ubuntu Oneiric server launched on Amazon AWS EC2. I made a new virtualenv and pip installed Django (1.4) and django-celery (2.5.1). I installed RabbitMQ 2.8.1 from the official RabbitMQ repository. I cloned the django-celery repository from github and added a single line near the top of the demproject's settings.py file: CELERYD_FORCE_EXECV = True. I then execute python manage.py celeryd from the command line. Commenting out the force_execv line results in celeryd starting up correctly.

2.5 backport of this is in the 2.5-backport branch,
I'd be very happy if you tested it by doing:

pip install -U https://github.com/ask/celery/zipball/2.5-backport

I missed your response requesting I test the 2.5-backport branch. I'd be happy to do so now, but that branch seems to have disappeared...
