I'm torn on that, mostly because I worked at a shop where sometimes bugs weren't handled immediately because they were edge cases (but we had more serious ones in play).
There was more than one time where a ticket from before I even started provided a critical clue, or at least a "We knew this was a problem and you didn't let us fix it" defense when the execs asked what happened. (Execs typically were the ones who forced us to add features instead of fix bugs)
