corrupt repository after following mq merging instructions

[L. David Baron]

So to merge my mq patch queue, I've been avoiding using the good
merging techniques documented in
http://hgbook.red-bean.com/hgbookch12.html#x16-28900012.8 because I
ended up with a bunch of problems the last time I tried.  I finally
gave it another try, and I ended up with a corrupt repository.  Is
this the result of a known bug?

Log of the relevant parts of what I did, plus my .hgrc, is below.
