I agree. This all sounds very much as if pdftex should check the
ArtBox, and fall back on the MediaBox if it's not defined. The only
question is whether this should replace the current CropBox check, or
whether it should be an additional level.

"MediaBox" is defined in the pdftex binary, so you cannot fix the
problem that easily.
