How to crash FireFox 3 with 3 lines of code

Hi there, here I am back from holidays :geek:

Before I'll start to write more interesting stuff, here we have 3 lines of JavaScript that could cause problems to our favourite browser, in this case version 3.0.1

I discovered this problem, already part of the bugs report site, trying to emulate keyboards events using the UIEvents interface instead of KeyboardEvents

var e = document.createEvent("UIEvents");
e.initUIEvent("keypress", true, true, this, 1);
document.documentElement.dispatchEvent(e);

Nice one? See you soon ;)
