Hi, Recent Icecat can't play some videos, like this one:
https://www.radioradicale.it/scheda/540252/operazione-black-job-illustrazione-dei-dettagli-del-blitz-contro-la-corruzione (thank you catonano for the link and for reporting it on IRC). Whereas an older one (say, /gnu/store/s85ykg7ggz8vlc0rf7ccjyz1af9n1q73-icecat-52.3.0-gnu1/bin/icecat) can play them. It should be bisectable. Cheers, Clément
