NLS/colormap weirdness

[Allin Cottrell <cottrell wfu edu>]

I'm trying to internationalize my (gtk-1.2) app, and I'm running into
the strange problem of the locale setting interfering with the
colormap.  I wonder if there's some known stupid thing that I'm doing
wrong.

I'm including below a small test case.  I compile this with
`gtk-config --cflags` and `gtk-config --libs`.  When I run the program
with LANG=en_US I see a little red Acrobat logo on the toolbar
button.  When I do 'LANG=french ./prog' the button appears blank: no
red design.  This happens with other icons too: red is lost, and
sometimes other colors.

#include <gettext.h>
#include <locale.h>
#include <gtk/gtk.h>

"16 16 2 1",
