- nautilus isn't installable until gnome-applets and control-center - which are currently waiting for a new libxklavier - are updated;
- you currently need to install gnome-menus by hand;
- a few packages are depending on experimental's libc6, therefore I didn't have a chance to test them.
The most annoying thing is that new menu: in French, it is called "Environnement de bureau", which is waaaaaaay too long.
