BABEL: RDF/XML to JSON convertion gives no results

Trying to convert an RDF/XML file, valideted using the W3 RDF Validion
Service, to Exhibit JSON format gives no result.
The RDF/XML file uploaded:

<?xml version="1.0"?>

The Babel raw data result:

{
"items" : [
],
"types" : {
},
"properties" : {
}
}

I converted the same file located at
http://www.sharesemantics.com/maps/swresources.rdf using the
http://triplr.org/ service that gave the following result:
