> If something goes wrong when reading an attachment it is really hard to find out what because the exception thrown does not include (or log) the cause of the error.
> See attached patch (or just this code snippet which fixes the issue):
> (line 155 - 165)
>              catch (Exception e) 
>              {
>                  if (value != null)
