{"failed": true, "msg": "'dict object' has no attribute 'ssh_key_passphrase'"}

I manage my users with the dochang.account galaxy role (https://galaxy.ansible.com/list#/roles/2104)

I was just trying the 2 branch today and got the error
{“failed”: true, “msg”: “‘dict object’ has no attribute ‘ssh_key_passphrase’”}

It works fine in 1.9.4. Any ideas/suggestions? Wrote to the author too.

Rolled back to 1.9.4 in the mean time.

According to http://docs.ansible.com/ansible/user_module.html the ssh_key_passphrase is not a mandatory variable.
