same happens for getters/setters, e.g.

var o = {
    exec: function exec() {
        var wtf = this.test;
    }
};

Object.defineProperty(o, "test", {
    get: function get() {
        alert(get.caller);
        return "test";
    }
});

o.exec();

Expected result: get.caller should be the function exec

Current result: get.caller is null

This happens only in WebKit ( latest nightly ) and Safari. It works as expected in every other browser.
The same thing can be reproducible via __defineGetter__ or __defineSetter__

var o = {
    exec: function exec() {
        var wtf = this.test;
    }
};

o.__defineGetter__("test", function test() {
    alert(test.caller);
    return "test";
});

o.exec();

Please fix this stuff and consider to put caller in ES5 specs since it is extremely important ( and you have it internally for scope resolution reason ), thanks.
