get requested url at NewWindowRequest or NewWindowCreated EventHandler

[Avi]

Hi
I am trying capture the url sent to the NewWindowCreated Event Handler.
private void webKitBrowser1_NewWindowCreated(object sender,WebKit.NewWindowCreatedEventArgs e)
{
Uri uri = e.WebKitBrowser.Url
// The uri is null
}
The e.WebKitBrowser.Url returns null . the same happens when at the NewWindowRequest Event handler
how can I get the url from the WebKit.NewWindowCreatedEventArgs ?
