Philippe, Is your patch still needed for newer version of gnome-terminal? The upstream bug you opened seemed to indicates your patch doesn't work. If this bug is still present, don't hesitate to reopen this bug, and if you can, to provide an updated patch (that hopefully works) for gnome-terminal-2.16 Thanks
