    prevent KDE/Qt from interfering with the session manager
    
    I occassionally get lockups in IceProcessMessages() called from QtCore,
    I'm actually not exactly sure why, as theoretically two connections
    from one app shouldn't be a problem, but since LO does its own
    session handling, there's no need to the KDE/Qt code to be involved,
    so prevent it from connecting to the session manager altogether.
