Can authenticate but unable to read remote filesytem

[Lucas]

The program installed correctly and the service is running, bound to 127.0.0.1. I also set `auth-url` to `https://auth.api.rackspacecloud.com/v1.0` in the default conf file. I restarted the service to get these changes.

I can authenticate with my username and API key, and see an `sftp>` prompt. Any attempt to navigate the remote filesystem fails, `ls`, `cd`, etc.

The log shows these types of errors:

ERR [20161125-01:24:36.080] thr=3 paramiko: unexpected error: list_folder('/',) from ('127.0.0.1', 50266): request() got an unexpected keyword argument 'body'
