I'm trying to create a Datasource from a GeoJSON file with no features, and Mapnik is saying that it can't parse that valid GeoJSON.

Looks like the error that throws originates here:

And through node-mapnik it comes out to me like this: Error: geojson_datasource: Failed to parse GeoJSON file ...

The file I've been trying just looks like this:

{
  "type": "FeatureCollection",
  "features": []
}

cc @mapsam and @jakepruitt, who chatted with me about this.
