Possible Bug with colonize same atmosphere?

[igoblin]

I have Version 1.41 with no modifications.

I started a game with both of the 'Only Colonize Same Type' and 'Only Colonize Same Atmosphere' options enabled. My race could only colonize Carbon Dioxide Ice planets. So I used troops to conquer some undefended Ukra-tal worlds in order to use their population do build new colonies where I could not. The Ukra-tal colonies are Methane Ice, so I assumed I could use my Ice colony ships to colonize Methane worlds with the Ukra-tal population. But when I try to colonize a world a window pops up saying that I can't colonize an Ice planet. This pretty much ruins the entire game as I had planned to expand by conquering enemy populations that could breathe different atmospheres.

Has anyone else had this problem or know how to work around it?
