I'll experiment with this when I have some time. Likely not tonight. If the above is true, then what's the tux file doing on the HD?

I did a double-take on the dithered beak and feet as well. Couldn't explain it. If your parser were pulling the file in incorrectly, it would show problems elsewhere. Plus, even though those parts were dithered, they were still outlined correctly - too selective for a load error.
