I suffer from this bug in a Karmic freshly installed. I edited the /usr/share/polkit-1/actions/org.freedesktop.devicekit.power.policy as stacktracer said but this is a workaround, not a real solution of this bug. Please confirm (if so) that even unchecking the can_hibernate and can_suspend box you still see the Hibernate and Suspend actions in the shutdown menu.
