Wierd.

Ruby should look for it first at Ingestor::Importer::Google::FileUploadHandler, then next at Ingestor::Importer::FileUploadHandler, all the way up to ::FileUploadHandler. I think it's the order of requires that is loading the Google class before FileUploadHandler which triggers rails auto-loading which is the issue. This, or explicitly requiring it ourselves should fix.

Anyway, no matter, it is what it is.
