Comment 12 for bug 1258521

This bug is happening with all files I converted using the latest calibre (version 1.16.0) and the latest kobo firmware (3.1.1), just with the kepub.epub files that calibre generates when sideloading the .epub files to my reader (Kobo Glo). I manually deleted the .kepub.epub file from the device and replaced it with a .epub file copied from the calibre library. The bug disappeared.
