How reproducible:

Steps to Reproduce:

2. Direct ansible to use winrm as per http://docs.ansible.com/ansible/intro_windows.html
3. ansible -m setup -i hosts windows

Actual results:
An exception occurred during task execution. The full traceback is:
Traceback (most recent call last):

    import xmltodict
ImportError: No module named xmltodict

w7-ansible-test | FAILED! => {
    "failed": true, 
    "msg": "Unexpected failure during module execution.", 
    "stdout": ""
}


Expected results:
Facts from the windows instance

Additional info:
On a sidenote it appears Fedora does not package pywinrm at present... but this particular import happens before the test that then says "you don't have winrm" which is a separate issue
