TypeError: Object #<Object> has no method 'is'

Hi everybody,

When I have a comment at beginning of HTML (comments are auto-generated by server), I can't use the Bold feature.

<!-- my comment-->
<p>TEST</p>

I have the JavaScript error : TypeError: Object #<Object> has no method 'is'

it's occurs in /core/dom/range.js line 1032

Until a solution is found:

 if(typeof(CKEDITOR) != "undefined")
        CKEDITOR.dom.node.prototype.is = function () { return false; };
