I have determined that (on my system) disabling the Nvidia video driver fixes this problem. When using the Nvidia video driver the following is found in the Xorg.0.log file:
Backtrace: 0: /usr/bin/X (xorg_backtrace+0x3b) [0x80e937b] 1: /usr/bin/X (0x8048000+0x61c7d) [0x80a9c7d] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0x393410] Segmentation fault at address (nil) Caught signal 11 (Segmentation fault).
