Shutdown command broken on Xenial

[PeterJCLaw]

I've just (in-place) upgraded to Xenial from Trusty and noticed that the Shutdown and Suspend commands don't work. However, having also just tried Lock Screen and Logout they do seem to work.

On looking in `/var/log/syslog` there are some messages which look like the *might* be related (I'm guessing based on these being session management commands and Do being a Mono thing).

The first try to shut down looks like it gave:

Aug 21 00:53:45 Behemoth gnome-session[4578]: [Error 00:53:45.719] [SystemManagement] Could not get SystemManagement bus object: Could not load type 'GNOME.SystemManagement+ILogindProxy' from assembly 'DBus.Proxies, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' because it is implements the inaccessible interface 'GNOME.SystemManagement+ILogind'.

Subsequent tries give:

Aug 21 00:54:21 Behemoth gnome-session[4578]: [Error 00:54:21.838] [SystemManagement] Could not get SystemManagement bus object: Duplicate type name within an assembly.

For reference I'm using the Compiz variant of the Flashback GNOME session rather than the default Unity one.

This is fixed by https://github.com/gnome-do/core-plugins/commit/8491a84edcb32345eda0950d33d4a77d28ad39db

@raof Will there be an DO update for xenial anytime soon containing the fix?

Could someone clarify when this becomes part of an official update, please? I guess having something committed doesn't translate to having it publicly available? Thanks.
