    Always show menu images (!32)
    
    There is a GtkSetting [1] that controls whether images in menus are
    shown or not.  On some distributions / desktops it is enabled by default
    and on others it is disabled by default.  To force show images in menus
    set the 'always-show-image' property to true in Gtk::ImageMenuItems [2].
