Why not? That's what can happen with bugs in the software. I've
encountered it too with F19 development (and ATI Radeon graphics).
Visiting "Settings > Power" in GNOME Shell, I disabled the screen blanker
(set it to "Never") or else I would return to the machine and fit it with
the monitor in power-saving mode and with no way to wake it up. It's not
supposed to be like that. It's misbehaviour. A bug somewhere. Currently,
everything is fine again.

In other words, people in this thread have misunderstood eachother.
"Locking" the screen does not refer to freezing the machine or crashing
X but just to displaying a passphrase prompt after you've left the
machine unattended for some time. That can be separate from the screen
blanker (or screen saver) activity. Neither should make your system
unusable. That's a bug.
