indicator-session-gtk2 0.3.93-0ubuntu1 (powerpc binary) in ubuntu precise

 This indicator is designed to be placed on the right side of a panel and
 give the user easy control for changing their instant message status,
 switching to another user, starting a guest session or controlling the
 status of their own session.

 It requires some way to be hosted into a panel. For the GNOME Panel the
 appropriate package is indicator-applet-session.
