Public bug reported:

I used google chrome to play the following video
https://youtu.be/pkAxZ8IhGEc    embedded on web site
http://www.wenxuecity.com/news/2015/10/23/4655677.html

The system just hanged.  I had to reboot.  It happened very time I
played the video in chrome.  I can play that video in firefox with no
problem.

I found combiz and chrome crash dumps at /var/crash    I can not use
apport to decode chrome dump.  I attached chrome crash dump in case
somebody can decode.  The following is the stack trace for combiz crash
