Xorg log from the crash

Description of problem:
After entering the password in GDM and hitting enter, Xorg crashes and brings me back to the GDM screen. This happens only when compiz is enabled.

The logs read:
Xorg[1891]: segfault at 0 ip 00000000004e8e0b sp 00007fff5d85fb18 error 4 in Xorg[400000+1b6000]

The problem starting occurring after applying a batch up updates on Sept 13 (see attached yum.log). There's also a new kernel oops that started occurring after applying those updates, which I suspect might be related to the segfault.

Version-Release number of selected component (if applicable):


How reproducible:
Always.

Steps to Reproduce:
1. Make sure Compiz is enabled.
2. Try to login.
  
Actual results:
Xorg crashes and brings you back to the login screen.

Expected results:
To be able to successfully login and arrive at the GNOME desktop.

Additional info:
The kernel oops can be found here: http://www.kerneloops.org/submitresult.php?number=714894

For others hitting the same problem, you can disable compiz from the console by typing: gconftool-2 --set --type string /desktop/gnome/session/required_components/windowmanager "metacity"

Comment 3 Staffan Gimåker 2009-09-14 16:30:22 UTC 
I'm still getting the same kernel oopses, so I guess that's not the cause of the problem.
Comment 4 Jeremy Fitzhardinge 2009-09-14 18:57:54 UTC 
I'm seeing this crash on login, but no kernel oopses.
Comment 5 Andrey Petrov 2009-09-17 07:19:37 UTC 
In addition, if you're not using compiz, and select System->Preferences->desktop-effects->enable desktop effects from the GNOME menu, you'll get the same crash and will be sent back to the login screen.
Comment 6 Luiz 2009-09-23 12:12:04 UTC 
Compiz still crashes X with default kernel parameters on grub.conf and sends back to gdm. 

But odd enough, booting without kernel parameter "quiet" compiz works perfectly! Confirmed multiple times.

Staffan's issue is a duplicate of 518748. Luiz's issue looks like a different bug.
