embedded ogv does not work on firefox 15 on 12.04+

[Jamie Strandboge]

In testing the firefox 15 updates for stable releases in QRT, I discovered that for both amd64 and i386 embedded ogv files no longer play on 12.04 LTS. Eg:
http://people.canonical.com/~jamie/totem-plugin-viewer-test/media-full.html
http://people.canonical.com/~jamie/totem-plugin-viewer-test/media.html

These work on earlier releases. On 12.04 LTS the browser reports:
"The Windows Media Player 10 (compatible; Totem plugin has crashed. Send crash report"

If I click "Send crash report" it looks like it was sent, but I don't know where. On 12.10 a crash screen is displayed in the window, and it says and clicking the crash screen icon (may require a page reload) says "an error occurred. Could not decode stream."

This may not be an issue with firefox per se (ie, it might be totem or gstreamer), but this is a regression over earlier releases and the 12.04 dialog is confusing for the user.
