When I visit the address http://www.2u.ee/eng/kalkulators_citizen_sld_311bk.html?3012.0.294
my Firefox 2.6.2 on Arch Linux completely locks up and I have to kill it. This occurs even with all browser plug-ins (Flash, Java etc) disabled.

Arch Linux basically ships the most recent version of all libraries. However, another person on Freenode #firefox also confirmed this problem on Ubuntu Karmic.


Reproducible: Always

Steps to Reproduce:
1. Visit http://www.2u.ee/eng/kalkulators_citizen_sld_311bk.html?3012.0.294
2. Spend a couple of seconds scrolling up and down.
3. The world is consumed by a black hole.
Unfortunately this stack trace is not so useful because I don't have debug symbols for xulrunner, but these are thread stacks at the time of the freeze:

The original site this was reported on has this JS:

	this.blink = function($item, $color1, $color2){
		if (this.$blinking.length == 0){
			window.setInterval("$main.blink()", 500);
		}

This causes a doubling in the number of running timers every 500ms.  That's bug 335256.

John, whatever you're seeing is a different issue....  at least assuming you see it on the login page I get when I load the url in comment 4.

Boris. Accepted. I now can't reproduce the fault consistently using that URL. My symptom probably arsies from a new bug or a different known bug. John
