[Barry Kaplan]

when running

    - debug: var=groups.control

    - name: Create facts.d directory on ops-control
      file:
        state: directory
        path: /etc/ansible/facts.d
      sudo: yes
      delegate_to: "{{groups.control}}"

i get

TASK: [debug var=groups.control] **********************************************
ok: [127.0.0.1] => {
    "var": {
        "groups.control": [
            "10.0.196.112"

    }
}

I've not yet seen this kind of error yet.

delegate_to does not take lists, groups.control is a list, you need to
give it a single item or use with_items to cycle through the list.

In any case this is a bug as you should not get a traceback, but a
nice error message that tells you something similar to what i said
above.

Ah, yes. Thanks!

This should be fixed in 2.0 (current devel)
