Check your libpng... With mine, there is no problem, no error message on the
console...

Also, try digiKam 3.2.0

Best

I have updated to digikam 3.2.0, my libpng is 1.5.16. All other programs, also
gwenview and okular have no problems opening the picture. I am quite sure this
is an issue in digikam...

Thanks for your help.

Sound like a regression in libPNG because here with libpng 1.5.13, there is no
problem...

Can you reproduce the problem with digiKam 3.5.0 ?

FreeBSD is still on 3.5.0, so I can't check right now, but I will as
soon as the port gets updated...

Thanks,

How do you generate this image ?

Can you share the original file to convert to PNG to try to reproduce here ?
