I modified a patch in comment #7 slightly. This patch calls display.getSystemColor() in setMessage() and in setText() and remembers it, and set it in gtk_expose_event().
Actually ExpandBar widget is doing the same as a patch in comment #7. So, either this patch or the patch in comment #7 would be ok for me.
