I ran into this problem at one point, too, but was in the middle of
trying to investigate a different bug and didn't have time to track
down what was causing it.

I think the basic question here is - if there's an error in the WAL,
how do we expect to EVER recover?  Even if we can read from the
archive or pg_xlog, presumably it's the same WAL - why should we be
any more successful the second time?
