Equal Height not working in Safari (jQuery)

Question

$.fn.equalHeight = function () {
    var height = 0,
        reset = $.browser.msie ? "1%" : "auto";
    return this.css("height", reset).each(function () {
        height = Math.max(height, this.offsetHeight);
    }).css("height", height).each(function () {
        var h = this.offsetHeight;
        if (h > height) {
            $(this).css("height", height - (h - height));
        }
    });
};

.. works great in Firefox and even the crappy IE6 but not Webkit (Safari, Chrome). How do I fix it?

Many thanks
