I tried /f IB.PAR+BUE.IOFR2D as well (with no dot after the f?). No dice.
Curiously it does work (with and without the PAR+BUE) if I untick "Only show flights with available seats"! (I actually managed to do what I wanted which was also to include a stop in RIO on the way back under the second fare at the same price, but only without checking for availability.)
Now I inspected the availability (as seen in LON) across each segment by hand with Expert Flyer and then as married segments: there's availability throughout. I couldn't actually check the ORY-MAD-SCL-EZE as one through married segment check though because of the stopover.
It also doesn't explain why the Matrix only finds the fare if you don't tell it where to look!
