    gtk3: crash on reusing a popup menu that has a sub menu
    
    Typically popup menus are created froms scratch each time, which is why
    this wasn't a common problem.
    
    To reproduce, under gtk3, set a template as default in the template manager,
    reset it using dropdown, now set another template as default, and reopen the
    menu.. it crashes
