Sure, attached you find the log (I didn't find a way to just pass those
variables to plugin-container, so I passed it to the parent iceweasel process).

Steps to get that log:
1. Start Iceweasel (aka Firefox) with the environment variables
2. Open a Twitch broadcast at some point within
3. Observed crash
4. Closed Browser.
