This one is pretty simple.
I have the following aspx page. All I do is redirect to any other page in reponse to a button click and there is crash deep in the javascript someplace. I am using the RadControls_for_ASP.NET_AJAX_2010_1_309 release.
Here is the text of the error message ( plase note the strange character at the end. That IS part of the message):

    
            Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.  
        
            Details: Error parsing near '?'.
