I tried to update my fedora rawhide with the updates of last night but had problems with the gnome parts. Apparently the new gnome-desktop brings libgnome-desktop-2.so.7 but some other packages (compiz-gnome, deskbar-applet, desktop-data-model) needs libgnome-desktop-2.so.2.
This is what i understood but i am far from being a specialist.
Regards.
