ubuntu-desktop is missing a few dependencies

Starting from a command-line (non-GUI) Ubuntu installation, adding ubuntu-desktop is supposed to be enough. But it is missing some dependencies. In particular, the indicator-* packages (indicator-application, indicator-appmenu, indicator-datetime, indicator-messages, indicator-power, indicator-session, indicator-sound). Without indicator-session, for instance, the GUI has no means of shutting down or rebooting (save for the command-line). Without indicator-datetime, the control panel has no Date & Time applet. (I'm still trying to figure out if some apparently-related packages such as gnome-panel, libindicate-gtk3, libindicate5, sni-qt or telepathy-indicator should be added or not.)

I suspect network-manager-gnome should be added in order to get the network indicator (or maybe indicator-network instead?).

The dash home is crippled unless the unity-lens-* packages are added (unity-lens-applications, unity-lens-files, unity-lens-music, unity-lens-video are the default set it seems).

The apt-xapian-index package is required for Synaptic to have a usable Quick Filter.

Finally, libgtk2-perl is something apt looks for repeatedly, and ought to be added as a dependency as well.

Addendum: gnome-screensaver and libpam-gnome-keyring are also missing. Without them, the system menu's "Lock Screen" command does not work.
