Ok, here we see: <Request "GET /newticket">
As opposed to #5286, id is not set by TicketModule.match_request, but as we're going into self._process_ticket_request(req) instead of self._process_newticket_request(req) in TicketModule.process_request, this shows that the id is set by some other means.
In #5286, it's projects/isound/report, here it's projects/isound/newticket, so there must be something in your web front-end that adds an id request parameter corresponding to projects/isound plus the value of the GET request.
It must be a misconfiguration of your web front-end, but it would be interesting nevertheless to understand what's going on, in order to see if this is something likely to happen for other people or not.
