Additional information

Here's the link to the file with which the problem occurs.

Thanks for reporting. It seems either the metadata of that EPUB file is invalid, or there is some problem when parsing it. Either way, it should not cause a crash (it doesn't for me) and should show an error message above the bottom navigation bar instead. I'm not sure why it caused a crash in your case. I'll investigate further to figure out both issues.

I've identified the problem. It was due to the EPUB file not using the exact tag names in manifest (.opf file) as described in the EPUB standard and adding an OPF prefix on them. I'll add handling for this edge case ASAP. Thanks again!
