Example URL: "https://www.larousse.fr/dictionnaires/francais/navigateur" Trying to open this URL (and many others) fails in all WebKitGTK-based browsers I could find in the Guix distribution. Surf and Nyxt report a crash, Epiphany hangs. The simplest test case is Surf. The command line guix shell --container --network --preserve='^DISPLAY$' --expose=/etc/ssl/certs surf nss-certs -- surf https://www.larousse.fr/dictionnaires/francais/navigateur runs Surf in a container, opening the URL cited above. The output is web process terminated: crashed Tested using Guix commit 32d5fb0, which contains WebKitGTK 2.34.1, but the same behavior is observed with WebKitGTK 2.32.4 (Guix commit a6ed7aeb2c).
