Description of problem:
Since installing updates from rawhide (as of Jan 10 and onwards), 
I am unable to shutdown the machine from the login screen. Reboot
works OK, but a mouse click on "shutdown" does nothing.

If logged into KDE or Gnome, I can do a reboot or shutdown, with
no problems, so IMVHO this is NOT a permissions problem.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Update system using packages from rawhide (as of Jan. 10 and later)
2.Login to KDE or GNOME, logout to login screen
3.Click on "shutdown".
    

Actual Results:  Nothing happens. Clicking on "reboot' will work, as will
clicking on shutdown from _within_ the window manager (KDE or Gnome).

Expected Results:  Machine should shutdown (same as it would if this were sent
from within
the desktop).
