This message is purely informational and doesn't indicate that anything is wrong. If an image build fails there will be a different error elsewhere that caused it. However, I have pushed a patch to remove this message during the cleanup phase so no one will be misled by it: https://review.openstack.org/#/c/186012
Ben, once this lands in midstream, please move this bug to modified. Thanks!
