Activity journal crashes on Ubuntu P

When trying to start the activity journal in P I get the following:

Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.zeitgeist.Log' on object at path /org/gnome/zeitgeist/journal/activity

When looking at d-feet I can tell that the interface is indeed missing.
