The test says:

12/17 17:12:05.138 ERROR|             utils:2763| Will raise error TestError('Video did not end successfully',) due to unexpected return: False

but in "messages" I can see some chrome crashes:

2018-12-17T16:46:59.833827-08:00 WARNING crash_reporter[8292]: [user] Received crash notification for chrome[7618] sig 4, user 1000 group 1000 (developer build - not testing - always dumping)
