Hi, in ZEORaid we switched from using `restore` to `store` for replaying transactions from another storage and found that the data records that FileStorage returns aren't filling in the `data_txn` fields correctly, but end up writing `None` all the time.
I'm not exactly sure how to fix this, but attached is a patch that makes it work for the cases I could come up with. I'd like to add this change to the trunk (I'll write tests if this change gets accepted).
