libpng warning: iCCP: known incorrect sRGB profile about froshwebp

[shyim]

Can you provide an image with is failing?

[Hotte512]

can i find them in any log ?

It looks like sw:thumbnail:cleanup surprised me and did remove some (original) article-pictures (jpg) there was also no webp generated, but cause the original is missing... but this can not create libpng iCCP Error.

This image are two files which disappeared after cleanup + generate https://cdn.holzundgarten.de/media/image/38/dd/08/401080_sandkasten_paula_1480x1256.jpg
https://cdn.holzundgarten.de/media/image/5d/dd/d7/SW10142_hangelleiter.jpg
but I think this might not be the files with the Color-Profile-Problem.

I'll setup a new test-system and find one, after fixing the cleanup mess...

update: I'll open a ticket for the thumbnail:cleanup...
I'll tell you if I found which has definitv the libpng warning: iCCP: known incorrect sRGB profile.

I also tried to find that files with https://stackoverflow.com/questions/22745076/libpng-warning-iccp-known-incorrect-srgb-profile
find . -type f -iname '.png' -exec pngcrush -n -q {} ;
find . -type f -iname '.jpg' -exec jpegoptim -n -q {} ;

I cant reproduce it with your given images 🙈

I have quite a few errors like that. If you could add the filename which causes this warning, I could run the generation again and provide you with these files.
Same with the error "libpng warning: iCCP: cHRM chunk does not match sRGB" and other libpng warnings.
