Not a fluke. Either the machine shop screwed up, the mechanic
(rebuilder) screwed up, or you got some bad parts. My guess is no one
paid enough attention to the crank. Did they replace or turn the crank?
I am assuming they replaced the oil pump. Did they clean the oil cooler
and oil lines?

I think you answered your own question "I wouldn't think so".

I would guess the first failure and the second failure are related only
if the rebuilder did not replace the part(s) that caused, or were damaged
by, the first failure (Jeez, that sounds like something my lawyer would
write). When they tear it apart *you* need to take a look at the
bearings and the crank. Ask them about the oil cooler (I assume your car
is equiped with one).
As for your warranty, I would think that an engine with 1200 miles ought
to have parts and labor covered.
