The PNG is invalid. Open it up in Photoshop and it will tell you the same thing I did - "the profile is invalid". (see enclosed picture)
In addition, I used one of my tools to dump the PNG structure to verify that the profile in the PNG is the same CMYK/4-color profile that you put in the PDF. Is that enough info to get your clients to fix their images?!?! OR, perhaps you could just do it yourself using ImageMagick.

What are you using to check the PNG? My problem boils down to the fact that the PNG looks OK because every application I've tried treats this as a valid image. Whether this is because they ignore the profile because it's invalid, or they just ignore profiles anyway is, of course, hard to say. Unless I can find something that will report a meaningful error on the PNG I doubt I'll be able to convince the user to re-do all of their images. "Insufficient data" is unlikely to suffice.
