Stuck on a black screen (wrong VT) after logging out of Gnome Shell

Stuck on a black screen after logging out of Gnome Shell.

Logging in via ssh shows gnome-shell is no longer running. But if I press Alt+F7 then the login screen (unity-greeter) comes up (and the login sound plays).

Curious. I can't reproduce this problem with artful today. Everything works better and I can't see what if any relevant packages changed.
