1245863 - FATAL ERROR: AsyncShutdown in Media shutdown: blocking on media thread

Status: RESOLVED DUPLICATE of bug 1228788

(Core :: WebRTC: Audio/Video, defect)

Description

[Ada [:adalucinet]]

Affected versions: 44.0RC build 1, 44.0RC build 3
Affected platforms: Mac OS X 10.9.5, Mac OS X 10.11.1

Steps to reproduce:
1. Launch Firefox with a clean profile.
2. Click on Hello button.
3. Click on Get Started.
4. Select 'Start a conversation'.
5. Click the menu button, click Help Menu and select About Firefox.
6. When prompted, click on Restart Firefox to Update button.

Expected result: Updates are applied and Firefox successfully restarts.

Actual result: Crash - bp-e72ed27b-ec5c-4c6f-8b59-e1be62160204

Additional notes:
1. Crash occurs when applying updates from: 
* 44.0RC build 1 to the latest 44.0RC build 3
** bp-62f9324a-def4-437c-b4ad-6b9332160204
* 44.0RC build 3 to 45 beta 2 (on 'beta-cdntest' update channel)
** bp-e72ed27b-ec5c-4c6f-8b59-e1be62160204

2. Reproducible when applying updates from 45.0a1 from 2015-12-01 to the latest 47.0a1 (E.g.: bp-5a08939d-3e8d-4523-a69d-1ca5f2160204), but it *does not reproduce* when applying updates from 45.0a1 from 2015-12-05 - maybe bug 1228788 is involved somehow with this report.

3. Terminal output when the crash occurs:

Need to investigate if Bug 1228788 regressed or if this is something new (unrelated to Mac + camera).

From the clarification in bug 1228788 (and the restated description here which corrects the STR) this is just bug 1228788.
