Actuall, I had exactly the same situation on a second machine, too.
From the files you are mentioning,

$ ls -l /var/log/dist-upgrade/
total 28
-rw-r--r-- 1 root root 2200 2007-05-30 14:59 apt-autoinst-fixup.log
-rw-r--r-- 1 root root 20043 2007-05-30 14:58 apt.log
-rw-r--r-- 1 root root 960 2007-11-19 19:47 main.log
-rw-r--r-- 1 root root 0 2007-11-19 19:46 term.log

only main.log was created recently, and contains:
