ah, here's the reason. In /etc/apt/preferences, I have (for purposes of testing out 8.04.1 CD builds):

Package: ssl-cert
Pin: version 1.0.14-0ubuntu2
Pin-Priority: 900

which leads to the following:

$ apt-cache policy ssl-cert
ssl-cert:
  Installed: 1.0.14-0ubuntu2.1
  Candidate: 1.0.14-0ubuntu2
  Package pin: 1.0.14-0ubuntu2
  Version table:
 *** 1.0.14-0ubuntu2.1 900
        500 http://security.ubuntu.com hardy-security/main Packages
        500 http://mirrors.cat.pdx.edu hardy-updates/main Packages
        100 /var/lib/dpkg/status
     1.0.14-0ubuntu2 900
        500 file: hardy/main Packages

And apt-get dist-upgrade will cause this package to be downgraded, whereas update-manager doesn't act on it. If I drop the preferences file, then update-manager is happy again.
