How to Reproduce

install trac 1.0 then install newest release of itteco trac plugin.

When you click on whiteboard roadmap or view tickets/ new ticket You get this error:

TypeError: _fetch_ticket() takes exactly 2 arguments (3 given)

I looked around for a similary problem. Is there any advice you may be have for me?

While doing a GET operation on /newticket, Trac issued an internal error.

You could probably just remove the db argument from _fetch_ticket. IttecoTrac is, perhaps out of perceived or actual necessity, working with a protected method of the Ticket class when it really should not. The db argument was present in Trac 0.12 but removed by Trac 1.0. More significantly, the last activity on IttecoTrac was ​> 5 years ago, so you may want to contact the author and inquire about the status, fork the plugin and maintain it yourself or try to find someone else who has forked it and is maintaining it, or stop using it altogether.
