    settings: Fix crasher with latest GTK+
    
    The way to set headers for GtkDialogues changes, and setting
    our titlebar in _init() might cause the default GtkDialog implementation
    to overwrite our widget, eventually leading to free-after-use problems.
    
    Create the titlebar in constructed instead.
