That is because in case of PNGs, there are not only color profiles, but
also gamma information [1]

I found in now :)

pngcrush did the trick, by not only fixing the problem, but reducing the
image size by 25% (in this particular case)

So I did a find . -name "*.png" and "crushed" all png found in the whole
TYPO3 source, with the result of 3.2MB compared to 3.6MB filesize of all
PNG images :)

Here's the link to the zip which can be directly extracted in the TYPO3
source directory.
