Comment 7 for bug 1559072

From what I can tell, this should also be a problem in openstackclient:

https://github.com/openstack/python-openstackclient/blob/2.2.0/openstackclient/common/exceptions.py#L125

And cinderclient:

https://github.com/openstack/python-cinderclient/blob/master/cinderclient/exceptions.py#L183

Unless it has something to do with the content-type on the request/response?
