I really thought all of these kahaDB index corruption issues were sorted, but if you can reproduce in 5.9 we have a problem that needs work. the key to any resolution is a reproducible test case.
In any event, you should be able to recover by rebuilding the index, just deleting the db.data file before a restart.
