When we use set_icon_widget(), GtkToolButton set a private property contents_invalid = TRUE [1], and gtk_tool_button_construct_content [2] is called. Then if the label widget not exist, a GtkLabel is added. This is a problem for us, by example in the Clipboard buttons in the frame. By adding a empty Gtk.Box instead of a label, we avoid the label creation. But as this is a internal implementation of Gtk, can change in the future, in fact the issue is not visible with Gtk < 3.16 This patch is based in a pr sent by Sam Parkinson [1] https://github.com/GNOME/gtk/blob/master/gtk/gtktoolbutton.c#L1415 [2] https://github.com/GNOME/gtk/blob/master/gtk/gtktoolbutton.c#L357
