Hmm. There is a fix for a slave-side-index-corruption problem in 9.1.6,
which is due to be announced Monday. I am not certain whether this is
the same thing though; that bug is low-probability as far as we can
tell (it would only happen if the master had been in the middle of an
index page split or page deletion at the instant of failover). Anyway
the first thing to find out is whether 9.1.6 fixes it.
