This would be caused by the TopicHistoryIndex not appropriatly getting selected, or an error thrown by TopicHistoryIndex which triggers a fallback to direct db query. The direct db query will always fail because topic_root_id is a denormalized value that does not exist directly in the database.
We may or may not want to solve this, it will also be solved by our existing plans to drop Flow\Data\Index\* in the next two months as part of the multi-datacenter work.
