Some more details from my side might be in place here.

The org.gnome.Vino schema dropped the "enabled" key in vino v3.14.0
(some time during 3.13.x to be more exact).

There are supposed to be no users of this in gnome 3.14.0.

(gnome-control-center 3.12.x used the key and I've already added an
appropriate Breaks in vino for it in the pkg-gnome vcs so it'll be part
of next upload.)

I've searched gnome-session but it (as far as I could find) doesn't use
this key. I suspect something else is hooking into gnome-session and
make it use the key.
Vino itself used to do this for example. See this:
https://git.gnome.org/browse/vino/tree/server/vino-server.desktop.in.in?h=gnome-3-12#n10

But since you have v3.14 of vino which is causing you problems,
you should also have the new vino-server.desktop file which no longer
contains the above.

I'm not sure what or why it triggering your problems and unfortunately
the backtrace didn't help me much. :(

Could you please check to make sure this file dissapears on your
system when you upgrade to vino 3.14.0-1:
/usr/share/gnome/autostart/vino-server.desktop

Maybe also "grep -R org.gnome.Vino /usr/share" and see if you can spot
something suspect.
