Scroll Lock key as screen lock hotkey does not work (works in U2D)

[Jani Uusitalo]

Steps to reproduce:
1. In (gnome-control-center) Keyboard settings' Shortcuts, set the shortcut for 'Lock screen' to Scroll Lock.
2. Press Scroll Lock.

What happens:
Nothing (screen doesn't get locked).

What I expect to happen:
For the screen to get locked.

What works:
* Setting 'Lock screen' shortcut to Shift + Scroll Lock, Ctrl + Scroll Lock etc.
* Setting 'Lock screen' shortcut to, for example, the Pause/Break key (which is right next to Scroll Lock on common keyboards).
* Setting Scroll Lock as the 'Lock screen' shortcut in Unity 2D.

Other notes:
Pressing Scroll Lock does nothing whether set as screen locking hotkey or not, so it shouldn't be tied to some other function either.

It (kind of) works in 13.10, but it takes a logout-login cycle or perhaps a full restart.
