This is an essentially a mis-feature in GtkPreview, which tries
to install a different colormap for the preview window, which
would only work if your hardware supports multiple colormaps.

However, things will work properly if you do:

 gtk_widget_push_colormap (gdk_rgb_get_colormap());
 gtk_widget_push_visual (gdk_rgb_get_visual());

before creating the colorsel. Take a look at testgtk.
