I have some HTML, which i am converting to XAML using the library provided by Microsoft

string t = HtmlToXamlConverter.ConvertHtmlToXaml(mail.HtmlDataString,true);

now, from http://stackoverflow.com/questions/1449121/how-to-insert-xaml-into-richtextbox i am using the following:

private static FlowDocument SetRTF(string xamlString)
{
    StringReader stringReader = new StringReader(xamlString);
    System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
    Section sec = XamlReader.Load(xmlReader) as Section;
    FlowDocument doc = new FlowDocument();
    while (sec.Blocks.Count > 0)
        doc.Blocks.Add(sec.Blocks.FirstBlock);
    return doc;
}

This however keeps crashing unfortunately =/ Does anyone have any clue on how to display XAML text in a RichTextBox please?
