Description of problem:
When using firewall-cmd, with and without bash autocompletion, I receive a python warning message.  The command passed to firewall-cmd still works as I expect it to, but the python errors are clutter.

Version-Release number of selected component (if applicable):
firewall-config.noarch                   0.3.13-3.fc22                   @System
firewalld.noarch                         0.3.13-3.fc22                   @System
firewalld-config-workstation.noarch      0.3.13-3.fc22                   @System
firewalld-filesystem.noarch              0.3.13-3.fc22                   @System

How reproducible:
Every time.


Steps to Reproduce:
1. Open bash shell as root
2. Attempt to use firewall-cmd to interact with firewalld.  For example, "firewall-cmd --state"

Actual results:
firewall-cmd --state

Expected results:
firewall-cmd --state
