[Note]:
- One time crash  

[Affected versions]:
- 63.0.3-build1 (20181114214635)

[Affected platforms]:
- Ubuntu 16.04 x86

[Steps to reproduce]:
- reproduced while having https://www.youtube.com/ playing on random videos for about 1 hour, with autoplay turned ON
- no heavy content websites opened (the other tabs were having Facebook, Gmail, Yahoo search, Web Skype and Amazon content)
- the Youtube tab wasn't in focus
- after a while, the audio provided by the Youtube tab stopped 
- focusing the Youtube tab, the content disappeared, being replaced by a white loading page 
- after 1-2 seconds, the Youtube tab crashed

[Additional notes]:
- I will continue investigating this, in order to find more accurate STR and regression related info
- I didn't manage to reproduce this issue on other platforms

Copied Jean-Yves so he'll see if better STR are added.
