gnome-session-properties no tabs displayed

[kolya]

Binary package hint: gnome-session

When I start gnome-session-properties I do not see any tabs, only list of applications to run at startup.
There used to be tabs which allowed to enable saving session, for example. Looks like they all disappeared after upgrade to Natty.
See screenshot attached.
