Hi,
Here is a patch for Chameleon on gtk to show the correct colours in menu. It solves "dark" themes problems where the menu text colour have to be in contrast with menu background(see "New Wave" theme introduced in Ubuntu9.04).
P.S.: This patch is specially made for Mirek , maybe you may consider git(or others dvcs) and other specialised tools and make your life easier, so you don't have to apply patches by hand .
Andrei
