question on gtk_menu_item_set_submenu

[Allin Cottrell <cottrell wfu edu>]

I'm using gtk_menu_item_set_submenu to attach a little submenu to a 
certain item in a popup menu.  So far so good, but I'd like the same 
submenu to appear "beneath" more than one item in the primary popup 
menu.  When I call gtk_menu_item_set_submenu for a second time, with a 
different attachment-point parameter but the same submenu parameter, I 
see this at runtime:

Gtk-WARNING **: gtk_menu_attach_to_widget(): menu 
already attached to GtkMenuItem

Is this bad?  Should I be doing this in a different way?
(gtk version is 2.4.9)
