bug when filter is used

[dvic]

I'm getting the following error for GET requests when applying a filter:

Debug: internal, implementation, error
    TypeError: Cannot read property 'key' of undefined
    at Object.<anonymous> (/Users/damirv/hapi/node_modules/good/lib/utils.js:93:69)

I've set up a sample app that shows this problem: https://github.com/damirv/hapi-good-filter-bug.

Am I missing something or this a bug? It seems that applyFilter is being passed null for data.
