You can find out for sure by testing Calibre from before that change: `guix time-machine --commit=262a1734e250f756471a066348381017b3e281d6 -- shell calibre` ... because that commit 262a1734 immediately preceded the removal of Calibre's transitive dependency on QtWebKit. Well, I tested an old copy of Calibre myself, from around January 7, and it doesn't help with this bug. Did you check if this bug has been reported upstream? https://calibre-ebook.com/bugs
