If you take a look at the above file you will see
"Size of this preview: 240 × 240 pixels. Other resolutions: 480 × 480 pixels | 600 × 600 pixels | 768 × 768 pixels | 1,024 × 1,024 pixels | 10,000 × 10,000 pixels."
The last item (10,000 × 10,000 pixels) doesn't render anything as wikimedia settings chops rescaling at 2,000 × 2,000 pixels I believe, which is fine. Therefore the presence of 10,000 × 10,000 pixels is problematic since it renders nothing (or it renders an error).
