NullReferenceException on XmlReader.Create


This bug was introduced with version forcing me to return back to version

When calling the method System.Xml.XmlReader.Create from inside a page that requires authentication, the setver returns "500 Internal server error"

Looking at the server logs, that's tha error call stack

Exception information:
Exception type: NullReferenceException 
Exception message: Riferimento a un oggetto non impostato su un'istanza di oggetto.
