I tracked down the problem. It seems that the original code tried to come up with a plane parallel to the cylinder axis oriented towards the eye/pick point. This calculation breaks down when the eye and cylinder axis are close to being parallel. I have fixed the problem and will be submitting a patch within the next day. I am trying to go through the code to do more cleanup as the original has a number of code paths that are never reached.
