Can someone enlighten me on why the following transaction is being rejected
by Bitcoind 0.9.1 with error code -22 on Mainnet.

01000000015594a8c1f84b926e84d70c3a3d5e517e0c12dc07cb1a774b587121fef08f91b8000000006b48304502202f534407f6dee4d8932ec22491cbc15a2d31af2bade4e8d417e4b1955de57f5902210086e2f0210c16ffff9b85074429b1b1c2f32e19509d7ed19f7804ab7212bd183a012102add59262e234c0045d1f6a3d40a144b47ea0b4214916f55fb6029a079cc0b3cbffffffff0358020000000000001976a9140f763005e063382f8f4138f75cdc64d14f8ec16f88ac00000000000000000a6a054f4101000102753d60860000000000001976a9140f763005e063382f8f4138f75cdc64d14f8ec16f88ac00000000


Debug.log shows the following:

Here is the decoded transaction:

Outputs are above dust, inputs are not spent. OP_RETURN is supposed to be
standard in 0.9.1 and the data is well below 40 bytes, so why is this being
rejected?
