    generate-introspection.py: Add the problematic filename to XML parse exceptions
    
    Registry.xml had malformed XML; this is fixed in the commit that
    removes "name" attributres from the the toplevel node elements.
    
    However, to catch invalid XML in the future, we do it in the Python script.
