The blank line indicates where there was a delay of a couple of seconds between ping responses. However there were no missed responses (icmp_req goes from 459 to 460) and the time is shown as only 0.120ms. So why was there a delay of a couple of seconds at this point?

Why do you think that?
You are assuming that an echo packet was sent, then there was a delay, then the echo reply was receive,d and finally the screen was updated.
How do you know that before sending echo packet 460 your computer wasn't momentarily busy, a background process fired up, something was writing to the hard disk etc, so the traceroute program paused momentarily perhaps?
