Nope can't say i do. Stumbled on it while debugging another issue I was 
having. But the palette is later allocated using:

rect->rgba_palette = av_malloc((1 << region->depth) * sizeof(uint32_t));

So unless you know how many colors there are in the palette, you end up 
risking accessing non allocated data, if the actually image data contains 
references to palette colors outside the number you have allocated.
