Summary: window.open() cause javascript exception

Initial Comment:
I am runninig the following code now:

>>>
HtmlAnchor link = ...

WebWindowListener windowEventListener = new 
WebWindowListener() {
   public void webWindowContentChanged
(WebWindowEvent event) {
       log.warn("webWindowContentChanged called");
   }
           
   public void webWindowOpened(WebWindowEvent 
event) {
       log.warn("webWindowOpened called");
   }
};
       
webClient.addWebWindowListener(windowEventListener);
       
link.click();
<<<

where link has the following on click attribute: 
onclick="javascript:var win = window.open
('','versionWindow','height=500,width=650,top='+
((screen.height-(screen.height/1.618))-(500/2))+',left='+
((screen.width-650)/2)+',scrollbars,resizable');win.focus
()"

This code throws an Exception: what I see is:

Additional information (probably has nothing to do with 
the bug): the page that should appear in the new 
window contains 3 frames.
