Hi,
Just wanted to let everyone know that we updated Mediagoblin to work with the latest celery and kombu versions. This means next time that you fetch from master that you need to run ./bin/python setup.py develop --upgrade.
In the latest version of Celery, BROKER_HOST has been deprecated and replaced with BROKER_URL, so make sure to update your mediagoblin_local.ini file as well.
Thanks
RJ
