I found what is wrong.  In x_load_resources (xrdb.c),
default values of several X resources are set, but fontSet
is not set.  But, in x_update_menu_appearance (xfaces.c)
which is called when you set `menu' face, the fontSet
resource is set.   That's why executing
        (set-face-font 'menu (face-font 'menu))
makes the menu label display correctly.

I've just installed the attached patch for 23
(emacs-unicode-2 branch).  Could you please confirm that the
change surely fixes the problem in your environment too?

By the way, I think the relevant code should be improved to
reflect a font specified for menu bar in a created fontset,
but, for the moment, I don't have a time to work on it,
sorry.
