Workaround is only partial as it ignores /etc/apt/preferences.d/ in favour of the plain /etc/apt/preferences:
$ sudo rm /var/lib/synaptic/preferences
$ sudo ln -s /etc/apt/preferences /var/lib/synaptic/preferences
(might need to
$ sudo touch /etc/apt/preferences
if it doesn't already exist)
Still broken in Lucid.
