Hi,
take for a spin gnome 3.2 from testing and report any packaging bugs to our tracker.
TUs, check your packages and rebuild for eventually soname bumps(e.g evolution-data-server).
NVIDIA users be aware that xorg-server 1.11 from testing is incompatible with the current nvidia driver, even with IgnoreABI. You can switch to nouveau or add xf86-input-evdev xf86-input-synaptics xorg-server-common xorg-server to Ignorepkg.
