The X server segfaults when certain X apps are invoked (eg. the Gimp, Firefox, Thunderbird which all use Gtk). With simple X apps (eg. xterm, xcalc) there is no problem.

Before reporting problems, check http://wiki.x.org
to make sure that you have the latest version.
I have rebuilt the X server from source using the Distro's build scripts but with CFLAGS=-g -O0. I have no /etc/X11/xorg.conf or /etc/X11/xorg.conf.d files. Xorg is invoked by kdm using '/usr/bin/X -br -novtswitch -quiet :0 vt7 -nolisten tcp -auth /var/run/xauth/A:0-2EbFha'. Following is the last part of the Xorg.0.log file. The complete file is included as an attachment.

Gdb debugging session: Attaching gdb to the running /usr/bin/X process and starting the Gimp to trigger the segfault reveals more information. Please see the attached file.
Please let me know if any other information is needed.
Thanks for your help. Tom Crane.
