It is possible that the Kobo Deluxe author intended for the use of the comments section on that packages page to be used to report bugs; "tunk.org" being used to redirect to the latest packages page when a new version comes out.

It is not required to have a "bugs.maemo.org" entry as your bugtracker link. I just use "mailto://".

**** what I wrote above - I just read that wiki page...
