Critical Celery 4.0.0 release has broken fresh installs - No module named timeutils
We do not explicitly set a celery version in:
https://github.com/sourcefabric/Booktype/blob/master/requirements/_base.txt
Celery 4.0.0 was released just three days ago and may have broken the install, since django-celery does not support this version of celery.
Andrew Falgout reported an issue very similar to https://github.com/celery/django-celery/issues/491
./manage.py syncdb resulted in:
