broken systemsettings

Trinity freshly installed on a HTTP Lucid minimal install, several modules are complaining about libpython2.6.so not found in paths, even though libpython2.6 is installed. One such is system services.

Why is there a main menu item "system settings" that opens systemsettings, even though KControl is installed?

KControl only shows the KControl start page when any of Monitor & Display, System Services, User Management, Windows Applications & others are selected.

Opening Login Manager causes message "unable to create folder /usr/share/apps/kdm/faces", which isn't surprising given that KDM shows no icons in the user list.
