Possible bug in ticket status upon user edit?

When a user edits a ticket, the status does not get set to $config->ticket_status_when_customer_add_comment because $data is undefined. This occur when using the email link for unauthenticated edits. I have not tested against authenticated. Here's the patch I've applied on our end:

ndex: Ticket.php

         }
         else
         {

The second edit could be skipped. We don't want a new ticket to have anything other than new, even if a user edits (they might be providing more information).

Thank you.

Hello

Could you please give us more information about this. Exactly what's user edit ticket? And how it happens?

Could you please let us know step by step what we need to do to see this case so that I can check this further?
