I am still getting this.  I have the most recent keyring:

$ pip show keyring

Name: keyring
Version: 3.4
Location: /usr/local/lib/python2.7/dist-packages
Requires: 


This is a DevStack install of OpenStack onto an Ubuntu 13.10 machine.  This shows the vintage of the python-keystoneclient (it was around Feb 12):

$ git branch -v
* master 5b3342d Merge "Fix debug curl commands for included data"


Here is a typescript showing the problem happening:

$ keystone help
