Beaker publickey - test fails

[oloc]

When we pull request, there's a beaker error. And I cannot find out in the web how to deal with this message by myseilf. Maybe an administrator should have a look at this.

Fetching git@github.com:puppetlabs/beaker.git

Can an administrator validate the PR #60 in order to close this issue?
