Bug#729206: kde-plasma-desktop: Screen locker does not allow opening a new session until opened otherwise

[Shai Berger <shai@platonix.com>]

Package: kde-plasma-desktop
Version: 5:82
Severity: normal

Dear Maintainer,

I just upgraded my system and got a substantial part of kde-sc 4.11.
Following the upgrade, I opened a session, then locked it; the lock
screen showed a password prompt with the "unlock" button, but the
"switch users" button that is usually there was missing. Only after
I unlocked, and used the "switch users" action from the menu 
(I use Lancelot) to open a second session, the button became available
on the locked screen as well.
