Hi, 
with last kernel 3.x I have a segfault of X server (v. 1.13.0).
When i start X (on kde4 or gnome3 environment) all start correctly. I have a
CRT monitor that support 1600x1200 resolution. Through these steps i have
always segfault:
1. X started with a resolution of 1600x1200
2. Change resolution to 1280x1024 (here resolution change correctly)
3. Change resolution to 1600x1200 (here Segfault)

(EE) Segmentation fault at address 0x8

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

Same segfault happens if I leave my computer on poweron but with monitor on
poweroff. When i poweron monitor screen resolution automatically go to 1024x768
and then when i try to restore 1600x1200 resolution I have same segfault.

Hereinafter same informations about my env:

# uname -a
Linux golia2 3.6.0-rc6+ #1 SMP PREEMPT Sat Sep 29 11:29:58 CEST 2012 x86_64
Pentium(R) Dual-Core CPU E5200 @ 2.50GHz GenuineIntel GNU/Linux

# lspci | grep VGA  
01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce GTS 250]
(rev a2)

Mesa-9.0 and libdrm 2.4.39.

This error happens with both vanilla kernel or nouveau-kernel from git.

How can i help you to fix this bug ?
