The PNG file is broken and can not be loaded by any image loader.

This problem comes from a buggy version of Exiv2-0.26 / 0.27. The problem will
not be resolved until Exiv2 > 0.27. This also affects Darktable when you write
metadata in PNG files. At the moment I am considering to handle digiKam PNG
files like RAW files. At the moment I can only advise against writing metadata
in PNG files. The ICC profile can be destroyed if the profile name is
different from the standard.

Here libpng giving up. The problem could have been caused by the previous
error.
