The assumption here is that if (rc != 0) in normal operation the errors are serious enough to warrant crashing the process, not handling it gracefully. Granted, I've just discovered one case where this isn't true, but that's when indexing is disabled and the db file shouldn't exist, so I've added a special check for that.

Also, that patch prevents an empty index from being created even when indexing is disabled, which is correct behaviour.
