It is likely that you placed your new component at the beginning of the file. This would mess up the given techs at the start. Try moving all your new components to the end of the file, and watch out for double blank lines, as SE4 dosen't take them well.
I tried adding the component in as the Last thing in the components.txt file and it still generates that error with races having a colonizing tech that does not match their setup. No matter which environment you pick for your homeworld it always gives you gas giant colonization as your starting tech.
I'm fairly sure it's not a typo, this is the second problem I've run into in which something that should be ok generates a weird error, from my experminting it seems you can't add climate control facilities to the AI's facility construction queue. I've written Malfador to see if it's some sort of safety precaution written into the game engine. Well here's the component, maybe someone can see an error in it that i've missed?

I had the same idea just prior to the 1.30 mod release. It seemed to work OK before but now seems to not work at all.
I think that maybe the mod did something that stops this from working.
Well, I copy/pasted your tech into my game and whaddaya know - it works.
I don't have any idea why this doesn't work for you but I had no errors at all and could colonize all planets with it (I used UFP - Rock/Oxygen race). It gets even better - AI is also putting this component on all of its colony ships.
Weird, weird, weird. Wish it would work for me. I was hoping that the AI would use the component so it could simply things for itself a bit. Well least it works for someone.
