    Fix gtk settings initialisation
    
    We need to ref some gtk classes before setting the gtk settings,
    since these properties are only installed by the various gtk classes
    at class initialisation. See gtk bug #585024.
    I think this wasn't noticeable on maemo3 due to the special launcher
    which already had initialised gtk before the fork.
