The one with your backtrace shows that this particular xorg version uses an internal function of FreeType which has changed. I think David T. can answer this better (after returning from his vacation) since he has already written some patches for main applications to avoid FreeType internals. The other problem (reported by James) could be a different bug, probably in the cmap code of FreeType, and for his particular problem I would like to see a backtrace. Werner
