After some more digging, I found some more possibly relevant information: - when installing current version of `fontconfig`, it also prompts to install various `pulseaudio` related libraries. - the `pulseaudio` libraries are currently version `1:11.1-1ubuntu7` - the `pulsaeudio` libraries currently installed in the docker image used in CI is `1:11.1-1ubuntu5` The update from `1:11.1-1ubuntu5` to `1:11.1-1ubuntu7` occurred on 2020/05/02: http://changelogs.ubuntu.com/changelogs/pool/main/p/pulseaudio/pulseaudio_11.1-1ubuntu7.7/changelog APT no longer shows the older version as available. I'm not certain if the upgraded version has anything to do with the odd crash. It seems like more than a coincidence that I began encountering issues with `mochitest-media` crashes on 2020/05/02 GMT though.
