Bug#682917: gstreamer support still not enabled on 24.0-1

[Martin Perazzo]

After updating  i went to http://www.quirksmode.org/html5/tests/video.html
Test video for h.264 failed to load with a MIME type not supported message
A quick look through iceweasel and xulrunner dependencies revealed no 
gstreamer packages.

Looks like gstreamer support wasn't properly enabled.
I request for the bug to be reopened
