"cinder credentials" returns error

[Eric Harney]

$ cinder credentials
ERROR: list indices must be integers, not str

A more useful traceback (only available by modifying cinderclient, currently):

    Print backtrace for exception when in debug mode

    If the cinder shell is run in debug mode
    (CINDERCLIENT_DEBUG is set in the environment or
    with --debug), print a traceback for unhandled
    exceptions.

    This makes it possible to debug issues like this:
      $ cinder credentials
      ERROR: list indices must be integers, not str
