Keystone erroring out on an off with below exception. I see that /usr/lib/python2.7/dist-packages/oslo/config/cfg.py", line 1782 expect self._args None and if not, it just throws this exception, when this happens, I see self._args value is set to empty list. I was working with Rohit to fix this and adding empty list to the condition actually fixing this error.

>>> The following change is fixing this issue
