Received a report. Looks like objectProcessor starts before sqlThread is ready. I can't actually reproduce it, it probably only happens ~if the objectProcessorQueue isn't empty~ under non-deterministic conditions. The problem was revealed in 184664d758. The solution is for the objectProcessor.__init__ to wait for the helper_sql.sql_ready event.
