If I recreate the submenu for each new instance of the menu, and reuse 
it for all menu items, nothing obvious happens, as the GUI still works, 
despite the GTK warning.

On the other hand, if I try to reuse the same submenu for all menu 
instances, it crashes even if there is only one menu item (putting a 
break in the loop).
