Switch User broken

Wed Aug 13 10:58:47 UTC 2014

KDE 4.13.3, Fedora 20 up to date.

Switching sessions to a different user works. Switching back to my
original KDE session doesn't. I just get a blank screen and have to kill
KDE or restart the system. AFAIK this is a recent bug as I have used the
switching feature with no problems over a number of years.

Could possibly be systemd-related, but that's just paranoia.
Has anyone else seen this or should I BZ it?
