Bloom has KeyError on 'groovy'

edit

I'm trying to release a catkinized repository, but getting an error when running "git-bloom-release groovy" (section 2.2 of this tutorial):

==> git-bloom-generate -y rosdebian --prefix release/groovy groovy -i 0

I have updated my packages, bloom is 0.3.5. I've also done a "rosdep update", and afterwards cleared out my temporary release repo and started over each time.
