/Some/ day I'll teach you folks to specify the version number when
reporting an issue ;)

If the scene parses, it's not an issue with `eval_pigment()`, as that's
called during parsing. Rather, the /scene/ created must have some
problematic properties.

Also, that's a TGA file you're using there, not PNG ;)

To further diagnose the issue, I'd probably need a copy of the image.
