Installed the plugin 'salty-vagrant-grains (0.0.2)'!

Expected behavior

What should have happened?

It seems to work, but I didn't expect all these ruby error messages

Actual behavior

What actually happened?

Despite the warnings, everything appears to work

Steps to reproduce

1. Install Vagrant 1.8.7
2. Run a plugin install command
3. See the ruby warnings

Have the same problem with vagrant 1.8.7.
Ubuntu 16.04.1 amd64

1. Download salt-vagrant-demo git repo.
2. cd salt-vagrant-demo.
3. Run vagrant status (will get warning).
4. Run vagrant up (will get exception).
   Back trace here:
   See gist for more info

I downgraded to 1.8.6 and this problem went away (as well as my other problem with being unable to add a box either locally or from the hashicorp atlas)

I think maybe 1.8.7 should be retracted!
