That indicates a corrupt sql file. I don't have any idea how it was
corrupted. The file in question is probably filechanges.sql.
Note that this is a cache of what contents changed in a given revision.
In discussing this with Michael Hudson quite some time ago, this only
exists because pre-2a format it was slow to answer the query of "what is
different between rev X and its parent". Since 2a makes that a fast
query, we can get rid of this cache.
I don't remember if I explicitly did all of that work in the
'experimental' code base, but I certainly pushed on it a little bit.
To finish it off, look for "FileChangeCache" and just remove places that
reference it. We don't need it any more.
