I was running into the same WARNING message and was able to eliminate it by replacing two files in the directory /usr/share/gconf/schemas. The files, control-center.schemas and gnome-control-center.schemas, were moved to .orig files. The source of the replacement files was this URL:
http://search.4shared.com/q/1/control-center.schemas After a re-install of update-manager, the WARNING was gone and desktop.en_US.utf8.cache was rebuilt: Unpacking replacement update-manager ... Processing triggers for hicolor-icon-theme ... Processing triggers for gconf2 ... Processing triggers for python-gmenu ... Rebuilding /usr/share/applications/desktop.en_US.utf8.cache... Processing triggers for desktop-file-utils ... Processing triggers for man-db ... Processing triggers for python-support ... Setting up update-manager (1:0.134.11) ... After a dpkg-reconfigure gconf2, there was no WARNING message. It may have happened during an Ubuntu update when gnome-control-center was also updated, since both the files were much larger and quite different from the .orig files. I have compressed the new files and attached them.
