Using grey colormaps

["Roberto A. Reyna Rojas" <reyna laas fr>]

Hello !

        I am trying to make a little program to display grey images, so
I do actually create a colormap and try to assign it to the main window
with the gtk_widget_set_colormap() fonction. It works but I have the
same message several times: 

Gtk-WARNING **: unable to allocate color: ( 30000 30000 30000 )

        I think that the origin is not  to the color values of the new
colormap, because for every different values I have the same messages.
In add because I use a "fileselection" widget, I have other messages
when canceling or chossing a file:
Gtk-CRITICAL **: file gtkstyle.c: line 575 (gtk_style_unref): assertion
`style->ref_count > 0' failed.

Thanks a lot.
