Hello dear gnome users,
in about six weeks jessie will be frozen, so developers are in a hurry to get latest gnome into it.
During the last night gnome 3.14 RC2 was uploaded to debian unstable (still continued, i guess).
and today on i386 gir1.2-mutter-3.0 breaks gnome-shell versions older than 3.13.92
Be careful with dist-upgrades!
greetings
musca
