Version-Release number of selected component (if applicable):
gnome-screensaver-0.0.23-3

How reproducible:
100%

Steps to Reproduce:
1.  Set screensaver preferences to Blank screen
2.  Click on Desktop menu->Lock Screen; screen goes blank
3.  Wiggle the mouse or press a key
  
Actual results:
Unbranded gray gnome-screensaver unlock dialog appears, with my user logo, gecos
name and username 

Expected results:
Some kind of Fedora-branded unlock dialog, preferably containing all of the
above elements. 

Additional information:
(If I set the screensaver to "Fedora Floating Bubbles" then the unlock dialog is
indeed branded, though why these should be linked doesn't make much sense to me)
