Dear Maintainer,

   * What led up to the situation?
Attempted to switch users from main Gnome menu and nothing happened.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I have two users on this system.  I'm logged in with userA and want to switch
to userB, leaving userA logged in with apps running.  I clicked switch user
from main menu and nothing happened.


   * What was the outcome of this action?
Nothing apparent happened in the UI.  No response in UI to my action


   * What outcome did you expect instead?
To be presented with the lightdm greeter to select a user to login.
