module fetch "Failed to template lookup" this bug?

[Andrey Fesenko]

Hello,
I'm have
[andrey@andrey ansible-test]$ ansible --version
ansible 1.9.3
  configured module search path = None

This host fedora 22, the same problem occurs ansible 1.9.2 and host FreeBSD

group_vars/local contain
[andrey@andrey ansible-test]$ cat */*
ssh_users:
  - name: andrey
    key: "{{ lookup('file', 'pub') }}"

hosts contain
[andrey@andrey ansible-test]$ cat *
cat: group_vars: Это каталог
[local]
andrey.local

If i run simplest run with fetch, run error

$ ansible -i hosts local -m fetch -a "src=.ssh/authorized_keys dest=authorized_keys flat=yes" -vvvv
<andrey.local> ESTABLISH CONNECTION FOR USER: andrey
andrey.local | FAILED => Failed to template {{ lookup('file', 'pub') }}: could not locate file in lookup: pub

If make blank file, fetch work fine

[andrey@andrey ansible-test]$ touch pub
[andrey@andrey ansible-test]$ ansible -i hosts local -m fetch -a "src=.ssh/authorized_keys dest=authorized_keys flat=yes" -vvvv

Why this can happen, the action also can not interact with this condition

[Brian Coca]

this is a bug in 1.9.x that any included vars files are templated even
when those vars are not used in your play (ansible creates a 1 task
play).

This was fixed in current devel (future 2.0).
