From reading your post (I'm not sure I fully understand it), the only problem you had was that pbuf_header() failed. You could have fixed this by not defining LWIP_ERROR to fail on error but just return the encoded error handler...
Anyway, I think I fixed this now. There were 2 places in IPv4 input where short packets could fail... Plus this report was for 1.3.2 and there have been many changes...
