Description of problem: I clicked on the link to an epub file for the OpenStack security guide: http://aa4698cc2bf4ab7e5907-ed3df21bb39de4e57eec9a20aa0b8711.r41.cf2.rackcdn.com/OpenStackSecurityGuide.epub Firefox saw okular has registered support for epub files & opened the file with okular. Happiness did not ensue https://www.berrange.com/~dan/okular-openstack.png Verified the document isn't damaged by trying the calibre program which displayed it without problems https://www.berrange.com/~dan/calibre-openstack.png Version-Release number of selected component (if applicable): okular-4.10.2-1.fc18.x86_64 How reproducible: Only tested with the above epub file Steps to Reproduce: 1. Open the above link in okular 2. 3. Actual results: https://www.berrange.com/~dan/okular-openstack.png Expected results: https://www.berrange.com/~dan/calibre-openstack.png Additional info:
Thank you for your report. It looks like this issue has already been reported at: https://bugs.kde.org/show_bug.cgi?id=318485 I added your OpenStackSecurityGuide.epub link there as another reproducer (the misrendering looks very much the same in both cases).
