LightDM - Jun 2015 - Problem with a non-0 autologin-user-timeout

I've installed the following in
/etc/lightdm/lightdm.conf.d/10-autologin.conf

[SeatDefaults]
autologin-user=mrsam
autologin-user-timeout=0

This works fine. The system boots straight into my xfce desktop, don't even
see the lightdm or lightdm-gtk-greeter.

But if I change autologin-user-timeout, say five seconds, I boot to the  
login screen, and nothing happens no matter how long I wait. A minute, a few  
more minutes, and eventually the screensaver kicks in.

May or may not be related: I was originally running gdm, with a timed  
autologin, but after upgrading to Fedora 22, the timed autologin stopped  
working in gdm, too. gdm's own greeter counts down the timer delay with a  
progress bar, and it was counting off the delay, as usual, but it was  
stopping when it reached the full length of the delay, and was not logging  
me.

So, since I switched everything on my desktop to xfce, except for gdm, I  
figured this was a good excuse to switch to lightdm. Configuring an  
automatic login was easy, but an automatic login after a timeout also isn't
working, apparnetly, for some reason, like gdm. Strange.

You need a higher version from the one in Fedora, in fact the latest version,
e.g.
$ rpm -q lightdm lightdm-gtk
lightdm-1.15.0-2.fc22.x86_64
lightdm-gtk-2.0.1-2.fc22.x86_64

Here you can find source rpms:
