Comment 1 Prasanth Anbalagan 2016-01-28 16:54:08 UTC

Looks like a similar bug had been filed upstream a few hours ago before this one.
Not sure if they are same, but the error message looks similar. Posting here for 
reference

This bug is against a Version which has reached End of Life.
If it's still present in supported release (http://releases.openstack.org), please update Version and reopen.
