X server crashes when browsing a certain website

[Binoy]

Binary package hint: xorg

I am not sure if this is a bug, but I can reproduce it here.
I am using Hardy, firefox 3 beta 5
my xserver crashes and sends me back to the login screen, when I browse some particular websites
Right now, i can reproduce the problem for the website
http://ubuntuguide.org/wiki/Ubuntu:Gutsy

this was found in dmesg after the crash

I have noticed the firefox-bin line is not always listed. So i am not sure if this is xorg related or something to do with the beta version of firefox. I was also able to reproduce the problem with firefox running in safe mode.

I am able to reproduce this as well. This is on a Dell XPS M1330 with nvidia GeForce 8400M GS. I am using the nvidia-glx-new drivers and I have compiz disabled.
