crashes, and resets X (back to login screen)

[LimCore]

Firefox crash on viewing soma pages.

ubuntu 8.04 amd64 (up to date)
firefox 3 (beta 5)
nvidia 8600 gt, nvidia drivers (glx-new)
NOT using Xgl, NOT using comiz (not installed) ; 1920x1200 LCD ; default Xorg config
nothing facy, clean system, all is default
amd64 dual core CPU

REPRODUCE:
Open http://tech.slashdot.org/tech/08/04/30/1822237.shtml click on the "One comment" link (or go directly to
http://developer.pidgin.im/ticket/4986#comment:272 )
If page opens then scroll it up/down for a moment.

In few seconds entire X crashes, always (and user is back at login screen)

Happened also on Xgl (but also without Xgl).

I seen some similar bug reports, but afaik none about entire X reset.
