    broadway: Quiet initialisation failures
    
    Broadway is the only GTK+ backend that throws an error on stderr when
    failing to initialise, which causes problems when gtk_init_check() is
    used and unexpected error output is generated.
    
    This causes hotdoc to fail when generating a GTK plugin's documentation
    instead of failing quietly.
    
    "Unable to init server: Could not connect: Connection refused"
