    ListViewAccessible: replace dynamic cast with static cast
    
    This cast may be the culprit of the cryptic exception raised
    which causes bgo#683498. Hopefully the reporter will be able
    to test again after this change to check if now an
    InvalidCastException is raised, or if what really happens is
    that the Parent property of the ListView is null.
