I would suggest trying a search on libpng invalid chunk type. You will get multiple hits.

I ran into this a couple of years back while working on some mangas. While almost all the image programs on my PC did not complain about errors when opening the images, libpng was very unhappy with them. pngcheck was a useful tool to locate the errors. The errors were mostly at the end of the file past the image data but several were scattered in the metadata or ancillary chunks.
