I have two tickets in helpdesk that are blank. However, viewing the actual email that contained the info from the ticket (I checked from the email I use for pipe), it is visible when I view the email/ticket through webmail, but on helpdesk it is blank.
I don't think it is a utf8 issue, it was just plain text, but maybe the user that place the ticket has an email client that adds extra tag info? strange, but in helpdesk it is not viewable. Please check into it and review.
