I've removed the first three (the ones derived from Listen
localhost:631) instead, in case listening only on 127.0.0.1 would
prevent other computers in the network from connecting to the CUPS
server, and now it starts and configuring finishes, so the problem was
indeed due to the doubled ListenStream specification.
