The problem is, libdbus is invoked from several places:
 - the DBus control plugin at stake here,
 - the inhibit plugin (or did we remove that already?),
 - the Telepathy plugin,
 - indirectly from the notify plugin,
 - indirectly from Qt4 UI libraries...

I don't see how we can tell say Qt4 to use our proxy object.

Even if we managed to interlock all libdbus calls, (un)setenv() could still
crash any other thread calling getenv() from any other (non-DBus) code
path... That was filed as FreeDesktop bug 27585 already.
