Output of okular when opening KritaManual.epub

SUMMARY
I've noticed that there are several similar bugs. I can confirm that some of them have been fixed and some are not. Now I've download a large epub file (about 74M, the krita manual), and okular always crash when I try to open it.

STEPS TO REPRODUCE
1. wget https://docs.krita.org/en/epub/KritaManual.epub
2. okular KritaManual.epub

OBSERVED RESULT
libepub (II): opening 'KritaManual.epub'
...
