ConsoleKit always thinks my session is not active.  As system policy requires that only the active session can perform certain useful functions (like turning off the computer), this is a major problem.

I'm logging in using GDM.  When trying to shutdown with GDM or from the Panel, I get the following message (this one specifically is from the Panel):
