With paramiko I get ImportError: Unable to import a GSS-API / SSPI module!

While trying to use the kitchen example https://testinfra.readthedocs.io/en/latest/examples.html#integration-with-kitchenci

I get a weird gss-api traceback

Am wondering if the problem lies in the following code https://github.com/philpep/testinfra/blob/master/testinfra/backend/paramiko.py#L65-L68 ... abrupty commenting it out get it to work...
