[Matthias Clasen <matthiasc src gnome org>]

commit aaef072fb9af5cba3c5a8d57d0454c706e41dc38

    Ensure icon themes are loaded with other themes
    
    Trigger icon theme loading from the code in GtkApplication
    where we set up the icon theme search path. This makes
    it happen before the first frame.
