    RssParser: Don't resolve external references (bgo#601554)
    
    If we were given the URL of an HTML page instead of a proper RSS feed,
    XmlDocument would then try to resolve the references to the HTML DTD,
    resulting in HTTP queries to w3c.org. Setting the XmlResolver to null
    prevents that from happening.
