 GNU ELPA has a 'debbugs' package that allows accessing the tracker

+Bugs needs regular attention.  A large backlog of bugs is
+disheartening to the developers, and a culture of ignoring bugs is
+harmful to users, who expect software that works.  Bugs have to be
+regularly looked at and acted upon.  Not all bugs are critical, but at
+the least, each bug needs to be regularly re-reviewed to make sure it
+is still reproducible.

+The process of going through old or new bugs and acting on them is
