undefined method `[]' for nil:NilClass (NoMethodError)

Working with some non-public data that was created by the catalog_preview module, I'm getting this error. I can provide the non-public data to a Puppet person or, if necessary, I can spend awhile sanitizing the data for public consumption. Let me know.

@hpcprofessional should be resolved with a8724cb, let me know and I will cut a bug release tag

[hpcprofessional]

Yes. The fix works for the test case. Thanks!
