    We utilize the telerik RichTextBox control within a large WPF application for editing HTML email templates we pull down from a web service.  

    One of the people in the office is receiving an error occasionally which is causing the application to crash when they load one of the UIs where the Telerik RichTextBox exists.  

    This is the exception message that is being logged:
