Ever since Firefox 3 was released into Centos 5.2, I've been able to
crash the Xserver by visiting the "System Messages" page on a
mediawiki server, such as these:


You can navigate there yourself if you like, just choose any mediawiki
on the Internet and go to "Special Pages" -> "System Messages". The
Xserver will crash before the page is finished rendering.

This used to work with wikipedia, but they've changed something on
their System Messages page so that it no longer triggers it.

I've checked this on an old box, and on a newer one. I don't know if
this is isolated to me, the radeon driver, or just to CentOS. I don't
know if RHEL is doing the same thing - I don't have one of those boxes
kicking around. The radeon_tp driver does the same thing.

This is the backtrace that appears at the bottom of the Xorg.0.log:

Anyone else notice this?
