gnome-shell-3.12.2-3-x86_64

* Fix CVE-2014-7300
* It was discovered that PrtSc key is not disabled when the screen is
* locked. Taking a bunch of screenshots at once bloats gnome-shell to
* the point where it's pretty easy to get it targeted by the kernel's
* oom-killer.
* This means that anyone with access to the keyboard of a locked GNOME
* session can (briefly) disable the lockscreen, which lets them see
* and interact with the running gnome session.
