Description Evangelos Foutras 2013-05-05 07:11:24 UTC 
I'm going to attach a tarball containing fixed copies of the affected PNG images, in
the hope that they can be included in a future release.

The error libpng 1.6 gives for the existing PNG files is:

"IDAT: invalid distance too far back"

Reproducible: Always

Reran optipng -o7 on them to further reduce their size.

Hi Evangelos,

I inserted the PNGs you sent into kipi-plugins documentation and digikam.

Thanks for sending them to us and best regards,

Michael
