.ToArray() and .ToList() methods on IEnumerable<T> results in "Object doesn't support property or method 'GetEnumerator'"

[GoogleCodeExporter]

What steps will reproduce the problem?

        private void ToArrayBug()
        {
            var sample = new jQuery("<ul><li>1</li><li>2</li><li>3</li><li>4</li>");

            var sampleEnumerable = from s in sample.children() select s;
            var sampleArray1 = sampleEnumerable.ToArray();

            var sampleList = new List<HtmlElement>();
            foreach(var s in sample.children())
                sampleList.Add(s);
            var sampleArray2 = sampleList.ToArray();
        }

What is the expected output? What do you see instead?
In the code sample, one should be able to use the Linq methods ToArray() or 
ToList() on sampleEnumerable; however this results an exception in jsclr-4.1.0 
at line 4211.
In the same example, a list created by iterating over the enumeration can be 
converted to an array with ToArray().

What version of the product are you using? On what operating system?

The example method is in a class with JsMode.Clr. The version is 4.29.9000 and 
the clr is 4.1.0.

This is because jQuery doesn't export a GetEnumerator method.
