Iceweasel or Konqueror + Kdm/Xorg turned into a cpu hog?

Hi

I have etch installed, regularly updated and running the KDE desktop environment.

Using either Konqueror or Iceweasel, I find that Xorg goes into overdrive when I access
this page: http://www.fasthosts.co.uk/login - reporting 92% usage on an Athlon XP 3200.

Closing the tab on that page immediately resolves the problem.

I'm wondering (a) if anyone else can repeat this and (b) why it's happening at all.
Can anyone shed some light?

Regards

L,
