--- Comment #7 from Gaëtan Gilbert <gaetan.gilbert at skyskimmer.net> ---
Does not work for me with okular 20.12.3 (debian testing, KDE frameworks
5.78.0, Qt 5.15.2, libpng 1.6.37-3)

Both attached cbz display the okular icon and output on stderr:

libpng warning: zTXt: CRC error
libpng error: PNG unsigned integer out of range
QImage::scaled: Image is a null image
libpng warning: zTXt: CRC error
libpng error: PNG unsigned integer out of range
QImage::scaled: Image is a null image
libpng warning: zTXt: CRC error
libpng error: PNG unsigned integer out of range
QImage::scaled: Image is a null image
libpng warning: zTXt: CRC error
libpng error: PNG unsigned integer out of range
QImage::scaled: Image is a null image

(the same thing for both files, on files without buggy images nothing is
printed)

Opening the images directly without the cbz wrapper works fine.
