I have a small application where i need to navigate to an url, I use this method to get the Frame:

public override System.Windows.UIElement GetPage(System.Windows.UIElement container)
        {
            XmlDocument doc = new XmlDocument();
            doc.Load(Location);
            string webSiteUrl = doc.SelectSingleNode("website").InnerText;
            Frame newFrame = new Frame();
            if (!webSiteUrl.StartsWith("http://"))
            {
                webSiteUrl = "http://" + webSiteUrl;

            }
            newFrame.Source = new Uri(webSiteUrl);
            return newFrame;
        }

My problem is now that the page im trying to show generates a error (or so i think), when i load the page in a browser it never fully loads, keeps saying "loading1 element" in the load bar and the green progress line (IE 8) keeps showing. When i attach my debugger i get this error:

System.ArgumentException was unhandled

Anyone? Or any way to capture it and respond to it, tried a try/catch around my code, but its not caught - seems something deep inside the guts of the CLR is failing.
