RE: WARNING Don't upgrade bonobo-activation packages

[Ephraim J. Lindquist]

If it helps anyone out, I have found that if you remove 
gnome-control-center before logging in, and then install it once you are 
logged in, you do not need to downgrade your packages.  Then you just 
open gnome-control-center and open the prefs you want set.  It will 
modify them instantly.
