Reproducible: Always Steps to Reproduce: 1. Load page http://srufaculty.sru.edu/david.dailey/svg/ovaling.svg 2. Firefox will become totally unresponsive and CPU will go to 100% (on one core) Actual Results: Unresponsiveness. Must terminate Firefox forcefully. Expected Results: A nice animation. As in Opera (even if it also drains the CPU to 100 % it still works. It does not work in Chrome 3 on Linux.)

Confirmed for Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.3a1pre) Gecko/20100123 Minefield/3.7a1pre

Structurally identical to bug 483584. I.e. use points to something which is animated.
