I still have PyQtWebEngine-5.13.2 here, and I haven't seen ebook-viewer crash with that. I now updated to dev-python/PyQtWebEngine-5.15.1_pre2006110847 and calibre still crashes. Maybe the Debian bug was pointing in the wrong direction. I downgraded all Python packages that I had for some reason in unstable versions and the problem disappeared. I don't know which particular one was responsible, maybe dev-python/PyQt5-sip. calibre is up to 7.x now, and has successfully migrated from Qt 5 to Qt 6. The suggestion above was that upgrading to a specific point release of PyQtWebEngine would solve the problem -- which is fairly typical IME with mysterious Qt-based crashes, namely that they are pretty heavily version specific. The linked debian bug report suggests yet another cause -- that it's about the compile-time private ABI getting out of sync... I'm assuming this is long fixed. I certainly cannot reproduce it. |
