We can re-apply the same patch, if we can verify it's the same bug. Sarah, can you crash X and post a fresh backtrace from Xorg.0.log (or Xorg.0.log.old) showing the backtrace? It sounds like this patch is relevant only if "glXleaveServer" is present in the backtrace. If it isn't, then this is a new bug we should report upstream ASAP.
