Which makes me think, this is a cinder issue.

Root of the problem is an horizon bug (even though Cinder should not return 500): https://bugs.launchpad.net/horizon/+bug/1469589

And it gets fixed in here: https://github.com/openstack/horizon/commit/faa44bfe1d6c4f342b8572bc4939771cda2039c7

As for Cinder, it should not return 500, so we need to we need to add filter validation (https://github.com/openstack/cinder/commit/8ba66fc5d2672bff69c21e36918e5e1882167649).  Some of the validations introduced in this patch are already in place, though some are missing on 7.0.

We need Horizon fix as well as the Cinder fix, because with only the Cinder fix Horizon will receive an empty list due to the malformed request.
