I know Tom alerted me to this a long time ago, but it was never fixed. If you have a comment thread with more than 1 comment, and you delete 1 comment from it, the link on your page will go back to zero comments ([add a comment]) even though there are still comments in the thread. Adding a new comment would reinstate the correct count, but of course you shouldn't have to do that.
Anyway, I believe this is now fixed.
