Hmm, that sure looks like the same issue Kyotaro HORIGUCHI reported
(http://www.postgresql.org/message-id/20121206.130458.170549097.horiguchi.kyotaro@lab.ntt.co.jp),
but that was fixed in 9.1.8. Maybe there's some corner case where it's
still not working.
Did you keep a copy of the WAL involved? Any chance of running xlogdump
on it, and posting the results, or just sending over the WAL files so I
could take a look?
