That LKML episode always makes me feel pretty bad. Mauro Carvalho Chehab maintains the ZBar project now. I briefly worked with him when I sent some patches in for a feature I wanted. There were things I had to address that I hadn't even considered and he worked with me all the way, ended up learning quite a bit about DBus. He's an awesome maintainer and set the bar for me for what qualifies as a great experience in contributing to free and open source projects.
