No it is not the sub emacs (into GDB) that calls dbus-launch, it's the
top level Emacs:

          - my .xsession launches "exec dbus-launch --sh-syntax
            --exit-with-x11 emacs"
            
          - Now I am in Emacs, I go to Emacs src directory and I do 'M-x
            gdb'

          - This gdb session launches another sub emacs to be debugged
