I'll see if I can recreate the scenario going back to dapper.
Regarding getting the same problem on Hardy by simpling installing and removing apache2.2-common; have you actually tried it? I have, and I wrote about it in my first comment.
Well, I guess there still might be the possibility of lograte rotating away the existing logs, and leaving /var/log/apache2 empty. I don't think so, but I guess I could take a closer look at exactly what the apache2 logrotate does.
