Barry, I just trying to use computer-janitor from your ppa. The first thing I noted is that your computer-janitor doen't offer me to remove linux-image-2.6.32-20-generic anymore, i.e. it only offer me to remove linux-headers-2.6.32-20. It seems to be an issue in the cruft searching algorithm.
Aside from that, your computer-janitor removed the linux-headers-2.6.32-20 package successfully.
