Hello Dave! If you haven't recompiled gerbv or anything like that, it sounds like there might be an bug in the Cairo libraries on OS X or XQuartz.
The trace you sent along doesn't say me anything really, maybe someone else? But if it works in the low quality modes and not hi quality mode I would look at Cairo. That is basically the only difference between these two modes. It would be interesting to know which version of Cairo you are running.
