The latter. Gwenview is not linked with any version of libKF5Kipi.so because, as it states on AUR page for both libkipi and kipi-plugins
please kindly uninstall kipi-plugins and libkipi, because they are defunct, deprecated, and not used by any application
If your Gwenview is linked with that library then it’s not from the official repositories, it’s from AUR or somewhere else.
