What it says, really. Looks suspiciously like what http://cgit.freedesktop.org/xorg/xserver/commit/?id=78f94f19aab66a1e5331df0ce29f36e310b4195d should be fixing, but I have verified the sources that this fix is included. I'm on ubuntu 10.10 with xorg-edgers ppa, specifically installing 1.9.2.901+git20101115+server-1.9-branch.201273a2-0ubuntu0sarvatt2~maverick. I'll make it crash in a few minutes and provide the Xorg.0.log file.

Kopete and GNOME system setting also crash X Additionally, I use prop. nVidia drivers (latest 180-series from ubuntu) on a 9800gt with two heads via TwinView.
I'm experiencing a similar problem, after upgrading to Fedora 15. In my case is a combination of using the Nvidia driver and Emacs. This is the stack trace Backtrace: [ 2141.819] 0: /usr/bin/Xorg (xorg_backtrace+0x3c) [0x80e8cbc] [ 2141.819] 1: /usr/bin/Xorg (0x8048000+0x5f846) [0x80a7846] [ 2141.819] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0x97b40c] [ 2141.819] 3: /usr/bin/Xorg (doListFontsWithInfo+0x11b) [0x8071d4b] [ 2141.819] 4: /usr/bin/Xorg (ProcessWorkQueue+0x31) [0x80759e1] [ 2141.819] 5: /usr/bin/Xorg (WaitForSomething+0x61) [0x80a0c51] [ 2141.819] 6: /usr/bin/Xorg (0x8048000+0x290ee) [0x80710ee] [ 2141.819] 7: /usr/bin/Xorg (0x8048000+0x1c38c) [0x806438c] [ 2141.819] 8: /lib/libc.so.6 (__libc_start_main+0xf3) [0x391413] [ 2141.819] 9: /usr/bin/Xorg (0x8048000+0x1c6a1) [0x80646a1] [ 2141.820] Segmentation fault at address (nil) [ 2141.820] Fatal server error: [ 2141.820] Caught signal 11 (Segmentation fault). Server aborting [ 2141.820] [ 2141.820] The version of Emacs do not seem to matter. 23.3, 22.1, 23.2, 23.1. All crash Xorg. Running emacs -nw works. Compiling emacs to use a different toolkit, other than gtk, also causes the crash. Removing the Nvidia library and using the default fallback video driver do not causes the crash. However, it is not running on the new gnome-shell. It is using the backup, the one that looks like gnome 2. The version of the Nvidia driver is 275.09.07. Driver in use is directly from Nvidia. kmod-nvidia and akmod-nvidia do not seem to work at all with gnome-shell. It crashes on login. Let me know if there is anything else I can provide to help.
I don't have time right now to find the specific Ubuntu bug report about this issue right now, but in it, it was suggested to uninstall xfs (X Font Server) if it was present through earlier installations being upgraded, and that seemed to solve at least the problem I was seeing. I'm not sure why xfs is a problem here, and haven't been following X development closely, but I guess it's been deprecated to the point that it now makes X crash...
Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
