I was able to manually upgrade mutter, gnome-control-center, and gnome-settings-daemon. The last two complained that libibus-1.0.so.5()(64bit) would be an unmet dependency. Still fail whale, session.log below.
unmet dependency are always always a sign of inconsistencies of the repos published or severe build failures....
** (gnome-settings-daemon:1189): WARNING **: libibus-1.0.so.5: cannot open shared object file: No such file or directory
Oh! Dang! IBUS bites us... that was expected. Please add the GNOME:Backports:Factory repository as well. We require ibus 1.5 (or 1.4.99) for GNOME 3.6... but as it's in RC phase only, the maintainers feel not safe in adding it to Factory...
** (gnome-settings-daemon:1189): WARNING **: Cannot load plugin 'Keyboard' since file '/usr/lib64/gnome-settings-daemon-3.0/libkeyboard.so' cannot be read.
Not sure about this one...

repository manages to rebuild and republish. If you need to recover
faster, then you have to:
get the new binaries of Mesa (osc getbinaries) from Factory
Build clutter, gnome-shell and gnome-session as a minimum against this
new Mesa package (osc co GNOME:Factory <pkg>; then osc build -p
