Bzr doesn't work without X if bzr-gtk is installed

[Lionel Dricot]

Connect on a remote computer with SSH and try to branch a bzr project. It will failed because X is not available. Current workaround is to ssh -X but it should not be the case : X is not needed to branch or pull or whatever.

bzr: ERROR: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ExecFailed: dbus-launch failed to autolaunch D-Bus session: Autolaunch error: X11 initialization failed.

bzr branch lp:elisa
