Bug#972715: atril: segfault on opening an epub file
Dear Maintainer,
I could reproduce this issue and attached patch avoids the crash.
This makes it possible to view at least some pages.
But there is still another issue with referencing the pages
containing a space in their names, which got encoded in
content.opf to %20, and atril encodes again to %2520.
I guess upstream needs to have a look at this epub.
Kind regards,
Bernhard
