When running KDE or a non-gnome ubuntu derivative, gnome-terminal is not available and the launch will fail if “Show Startup Console” is selected.
If you install gnome-terminal, it’ll still fail with the following timeout
$ # Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: Timeout was reached
