a web site that blows away my desktop session



  as a followup to one of my posts from yesterday(?), i've been
cruising the intertoobz, checking for other sites that seem to do bad
things to my f12 beta desktop session.  here's one -- a post from a
canadian political blog:

http://scathinglywrongrightwingnutz.blogspot.com/2009/10/difference-between-propaganda-and-facts.html

i am making no political statement with this, i am simply pointing out
a web page that will (in this case, at least) not take down my entire
system, but will kick me out of my gnome desktop and force me to log
back in again.

  note:  simply loading that page is not sufficient.  what i need to
do is scroll down two screens, then ... BOOM!  my desktop is gone.  i
have done this a few times, and it's entirely reproducible (including
the necessity for scrolling down a bit to cause the crash).  i am
looking at that page right now using firefox from a novell SLE 11
system, and it's fine, no problem, even with scrolling.

  i'd be happy to add some log file info to this, but i'm not sure
where to go looking for that.  can anyone else reproduce this?  i'm
going to guess it's related to the ATI video on this laptop:
