We have not a chance to make the global menu really configurable per
sessions?

If we don't have UBUNTU_MENUPROXY in our environment also could be
problematic. For example, if i'm outside of unity and i want to use the
unity-gtk-module in a third-party global menu implementation.

I will need to set UBUNTU_MENUPROXY=0 for all root sessions, not matter
if was launched with pkexec or gksudo or sudo, because root application
have not access to the com.canonical.AppMenu.Registrar.

Then the only solution will be to set UBUNTU_MENUPROXY=0 in
etc/environment and then probably in /etc/profile i will need to set it
to 1 again, but of course this will have some side effect in other
sessions.

Bug description:
  [Impact]

  The upstart script for unity-gtk-module causes it to run under all
  desktop environments indiscriminately when it should only be running
  under Unity. It does this by adding unity-gtk-module to the
  environment variable GTK_MODULES.

  In Xfce, this causes the panel to crash when trying to add Unity
  indicators, as well as other related side effects (see: LP: #1314782,
  LP: #1347272).

  The fix to ensure we only modify GTK_MODULES under Unity is already in
  14.10.

  [Test Case]

  Log into a Xubuntu session on a machine that has both ubuntu-desktop
  and xubuntu-desktop. Add the Indicator Plugin to the panel and open a
  terminal window. A crash dialog should appear notifying the user that
  the Indicator Plugin unexpectedly left the panel.

  [Regression Potential]

  The potential for regression is low since the only change is to
  preserve the original value of the GTK_MODULES environment variable,
  as well as to never set UBUNTU_MENUPROXY. The fix restores the desktop
  environment to its intended state of not running unity-gtk-module.
  Also, I've tested the change under Unity, and application menus still
  work properly under the global menu without regression.

  [Other Info]

  N/A

  === original bug report ===

  To reproduce: either start with a fresh Ubuntu install and then
  install xubuntu-desktop, or start with Xubuntu and then install
  ubuntu-desktop - ie have both Xfce and Unity installed on the same
  machine.

  Xfce now has support for gtk3 indicators launched by upstart, but
  indicator-appmenu is totally broken - it will constantly crash the
  panel and applications. Xfce has a mechanism to hide indicators, and
  then the frontend UI will not be loaded in the panel, but it seems
  that UBUNTU_MENUPROXY is still being set in Xfce, which causes menus
  to disappear from applications, even though nothing is available to
  receive them.

  I discussed this with tedg and he suggested that the problem may be to
  do with the upstart service which sets UBUNTU_MENUPROXY, ie
  /usr/share/upstart/sessions/unity-gtk-module.conf

  We may in future get the appmenus working in Xfce, and then we would
  need some way to turn the menuproxy on and off depending on the user
  configuration. But for now, since they are broken anyway, it would be
  easiest to simply blacklist xubuntu desktop completely.
