Videos no longer start in youtube with current trunk, but if I try to seek, I get a WebProcess crash with the following bt:

Looks like another duplicate of #191106

Debian testing has mixed versions of gst and plugins (1.16 and 1.14). I upgraded everything to 1.16 from sid and everything seems to be working, so let's close this.
