Comment 6 for bug 1652960

Yes, TEST.epub is supposed to have no image (or content) inside, just a link to a imgur picture.
I crafted it keeping only what gave the issue, so there's nothing exept that imgur link.

The "original story"; the epub is grabbed from a webpage with webtoepub (a browser addon), and it has content and pictures too, excluding when they are in the form of that link in TEST.epub.

That kind of plain links is like that in the original web page(s) too, so when the addon parses them it doesn't know what to do and leaves them like the one in TEST.epub.

I was using the "Download external resources" to try to those images automatically; now I know I have to change the tag before doing so. Many thanks for fixing the unhandled exception too.

I did ask the addon developer about parsing those kind of links, but for now it's not top priority since they're hard to "separate" from standard links.
