Yes, tricky indeed :-) What I mean by funny is that I tried to get the
GtkMenuItemFactory that was used to build the menu, but I couldn't find
one. It looks like glade builds all menus with gtk_menu_new and thing,
instead of using GnomeUIItems. Maybe I'm just stupid. Anyway, I managed
to get it to do what I want by making a part of the interface manually,
and that is enough for me.

No I haven't read it, but I think if I spend enough time I could write
it, but I just don't have the time so I was hoping that someone else
would write it :-)
So anyone on the list reading this, if you're bored this weekend, have a
look at it :-)

Ok.
