Description of problem:
/usr/lib64/firefox/firefox was killed by segfault in libxcb-glx.so.0.0.0

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 6.4

How reproducible:
Crash happens every time libvnc.so module is loaded in Xorg.

Steps to Reproduce:
1. Install tigervnc-server-module-1.1.0-5.el6_4.1.x86_64 package.
2. Create xorg.conf in /etc/X11/ with loading vnc extension. Below is the contents of xorg.conf file.

Section "Module"
Load "vnc"

Section "Screen"
Identifier "Screen 1"
Option "SecurityTypes" "None"

3. Logout from session and re-login/ Restart X
4. After Logging in, start firefox. X session crash happens and coming back to login screen.
5. If vnc module is not loaded, everything works as normal.

Actual results:
Firefox gets killed by segfault. And crashes the Xorg session. Crash happening in libxcb-glx.so.0.0.0

Expected results:
Firefox should start as normal. Xorg session should not crash.

Additional info:

The crash is happening at libxcb-1.8.1/src/glx.c +2444 in xcb_glx_query_server_string_string_length. The value passed is 0x0 for getting the string length.
Attached is the backtrace, Xorg.0.log, /var/log/messages .
