I am having the same problem (with different dates and using the cli version). [My post](https://bitcoin.stackexchange.com/questions/102659/upgrading-converting-bitcoin-core-wallet-between-platforms). Your situation seems to indicate that the problem I am having is not related to platform or gui vs cli, which is helpful (at least to me). So thanks.
