Receiving MMS fails if MMS contains only image (no text)

Moreover, as I already wrote, I discovered (and confirmed by multiple tests) that MMS messages sent from the iPhone 6s fail as long as there is nothing in the “Subject” field. If I send a plain image without subject, its reception fails on SFOS (and PDU decode error is in logs). If I add to it even just one letter in the “Subject” field, it is received correctly, without any PDU decode errors.

Could you send me MMS log of a successful reception?
