@romu: Happened the same thing to me, it is broken in Beta 2  13.10
I've actually added the gnome3-next and gnome3-staging PPA and it
fixed it, but other things get broken, so it's going to get fixed in
the next gnome3-next update, so it's not your fault, you have to be
patient for the update.

Good job testing!
