X locks up with Konqueror on comics.com

If I browse to comics.com using Konqueror under KDE on Fedora 11, X will, after a delay, lock up. The mouse will move, but no keyboard input is recognized, and the screen does not react to the mouse passing over objects on screen. I am able to ssh into the machine and issue shutdown -r now and have that work.
