Downgrade helps. gnome-shell is stable after that. libc-bin [2.13-22 (now, unstable) -> 2.13-21 (testing)] libc-dev-bin [2.13-22 (now, unstable) -> 2.13-21 (testing)] libc6-dev [2.13-22 (now, unstable) -> 2.13-21 (testing)] libc6-i386 [2.13-22 (now, unstable) -> 2.13-21 (testing)] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
