Hi, FYI, I've updated bug #537572 about gnome-settings-daemon eating CPU (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=537572).
I've also open bug report #620874 against ld about -z defs flag producing a broken gnome-settings-daemon binary (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620874).
