Could not load Energy Saver preference pane.

When I re-installed Lion on my Mac, I have "Could not load Energy Saver preference pane" error message when I'm trying to open Energy Preferences from System Preferences. I have the same problem with Desktop & Screen Saver as well as Spotlight. I've updated the OS to yhe latest version and installed the latest combo pack.

MacBook Pro, Mac OS X (10.7.4)
