Trying to run gnome-terminal produces this error (I wrapped the lines):

$ gnome-terminal
Error constructing proxy for
org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling
StartServiceByName for org.gnome.Terminal:
GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildSignaled: Process
org.gnome.Terminal received signal 5
