The problem related to Santa is already solved. He doesn't live in the US 
I think I begin to understand the other problem now. Despite of the specification in the last section header
('PEHeader', '0x5000', '0x400', '0x0' , '0x400')
The header does not seem to be mapped into memory. Is this the problem?
If this is the problem is this then a solution

Happy NY to you too and thanks for proposing the puzzle.
Can we conclude that a raw offset of 0 is not allowed in the sense that the section doesn't get mapped into memory, however, the loader (windows) doesn't complain about it either. Any raw offset in the range 1 to FileAlignment-1 seems to be truncated (rounded downwards) to 0!
