When I'm running "./bin/gmg dbupdate" I'm getting this warning, which apparently isn't fatal, but a bit scary and annoying :-) According to joar it's because it is run without CELERY_CONFIG_MODULE being set.

/var/www/media/local/lib/python2.7/site-packages/celery-2.5.3-py2.7.egg/celery/loaders/default.py:64: NotConfigured: No 'celeryconfig' module found! Please make sure it exists and is available to Python.
  "is available to Python." % (configname, )))
