Something has happened between 8.04 and 8.10 where 'recommends' are now being automatically pulled in. Apt-get install lokkit will pull in gnome-lokkit, which on a minimal Xubuntu system will pull in all the missing gnome libs, evolution-data-server etc., that a full gnome desktop would need. On 8.04 lokkit, IIRC, is roughly a 500KB install.

In any case 'sudo iptables --list' will show you your policies.
