plymouthd crashed with SIGSEGV in ply_renderer_set_handler_for_input_source()

I got this crash a couple of times on after I upgraded to Ubuntu 18.10. Every time I got this crash notification, it was at the first login I made into the system after I re-used it after shutting down the pc for a few hours.
