Comment 7 for bug 1561947

++ this is a fairly large issue for our deployment team because we back glance images to swift almost 100% of the time. I'm currently testing the patch https://review.openstack.org/#/c/297665 and will follow up on the review however in my opinion this should be a release critical issue for glance as it's likely to break a significant portion of deployments for both greenfield and upgrades.
