I have a 10.10 VM that I can test with. I built the latest pretest + the
patch you included here on 10.10 and ran it. There was no obvious
crashing. I tried double clicking some text, as the original bug report
(18993) mentioned that often caused the freeze, and I suffered no freezes.

If there's something specific you would like me to do, let me know.
