Bug#585149: iceweasel: Not all videos with Type == "video/webm" work

[Dave Witbrodt]

Package: iceweasel
Version: 10.0.1-1
Followup-For: Bug #585149


After updating to the latest 'iceweasel' in Sid, I had to restore my
old bookmarks and toolbar settings.  The clean .mozilla directory
caused a "Getting Started" button to appear on the toolbar, and I
found that mozilla.org is using WebM videos for their tutorials at
that link:

  http://www.mozilla.org/en-US/firefox/central

Clicking "Getting Started", then "Browsing Basics" runs a WebM
video... and I get no sound again.  Frustratingly, the Page Info here
lists the Type as "video/webm", but the Associated Text says "This
video requires a browser with support for open video or Flash."

By comparison, the WebM video at

  http://camendesign.com/code/video_for_everybody/test.html

(which works for me) lists Type as "video/webm" and Associated Text as
"Big Buck Bunny".

I have no idea why some WebM videos play for me, and why some do not!
