Send additional data in reported execption

I’m using SmartAssembly custom error reporting feature to report exceptions to my server. I’m having the following code snippet:

catch(Exception ex)
            {
                ex.Data.Add("some Info", msg);
                ex.Data.Add("info2",â€data2â€);
                ex.Data.Add("info3", “data3â€);
                SmartAssembly.ReportException.ExceptionReporting.Report(exception);
            }

When I try to read an exception from SmartAssembly error viewer the custom data added to the exception cannot be found!

How can I implement correctly some custom data in the error reporting?
