lookup error exception in /jinja2/environment.py" for apt_key module since last weeks commits

Yesterday I synched to the latest ansible head.
ad5731b4a80355dbf5aa26db495f60e2e88131e1

When I run the ansible-hadoop playbook
I now get failing errors below. Sorry I don’t have any
experience with apt_key to produce a minimal example here,
but the error msg looks fairly useful.

Hi Kersten,

Sorry you’re hitting problems on the development branch.

As per instructions on https://github.com/ansible/ansible/blob/devel/CONTRIBUTING.md please file bugs on github.com at github.com/ansible/ansible so we have a record of things.

Include all the information you’ve submitted above and we can take a look at why lookup plugins might not be working everywhere.

Should be an easy fix.

Thanks!
