Spec:

If a reflecting IDL attribute is an unsigned integer type (unsigned long) that is limited to only non-negative numbers greater than zero, . . . On setting, if the value is zero, the user agent must fire an INDEX_SIZE_ERR exception.
"""

"The size IDL attribute is limited to only non-negative numbers greater than zero . . ."

Test case:

<!doctype html>
<script>
    var el = document.createElement("select");
    try {
        el.size = 0;
        alert(el.size);
    } catch (e) {
        alert(e);
    }
</script>

Chrome dev on Ubuntu and Safari 5 on XP alert "1".  Recentish Firefox nightly throws an exception per spec, Opera 10.60 and IE8 alert "0".
