I always forget to do this. Long ago I installed
XQuartz on my Mac OS X 10.5 (Leopard)
desktop. For the life of me, I can't remember why I installed it. XQuartz replaces
the X11 that comes with Mac OS X. I might have done this since XQuartz is more
up to date than Apple's X11. Another possibility is that one of the two X11 apps
I use frequently (Gimp or
Wireshark) required the update. The reason doesn't
really matter, the important thing is to remember to reinstall XQuartz after
every Apple Software Update.
If you're experiencing this problem, you might see something like the following in your log files:

By the way, Snow Leopard users are not affected by this problem.
