<!--- Paste example playbooks or commands between quotes below -->
Run ansible and have a failure so you get the retry file

##### EXPECTED RESULTS
Ansible will run for just the failed hosts in the retry file

##### ACTUAL RESULTS
ERROR! Unexpected Exception, this is probably a bug: string index out of range
