It generates empty list of images:

Same command when used before for Pike/12 worked.
To generate non empty list, both sahara.yaml and cinder-backup.yaml had to be removed, just one of them still results in empty list.
List obtained after removing both can be see e.g. in other bugs attachment https://bugzilla.redhat.com/attachment.cgi?id=1382579 .

I can reproduce it on my dev box with the client and t-h-t installed/clonned from master branches, via pip/git.
It works though when --environment-files picked like from the services-docker/sahara.yaml and services-docker/cinder-backup.yaml (note: services-docker is used instead of just services)
Shall we change this to a docs bug perhaps?
