Issue 1:
Using Django 1.4.3, django-celery 3.0.11 and celery 3.0.16. In settings configuration I have USE_TZ=Yes and I am using redis as a queue manager.

After some time the server is running,

My celery is restarting every time showing this error:

Issue 2:
I believe this issue is supposed to be fixed in the versions of DjCelery and Celery I'm using, but I'm still getting TypeErrors thrown when I try any variation of python manage.py celeryd

Of note, I'm also using Postgre 9.1.9 on Ubuntu and a Linode server.

Here's the traceback:
