Two things changed in that upload:
 - the obsolete gconf file got dropped (sigh, I forgot to document that
   in the changelog). This change shouldn't make a difference, though.
 - gecko-mediaplayer now built against xulrunner-dev 17.0.6ers-1. Maybe
   that lead to an incompatibility with iceweasel 10. I think I found
   the culprit and a fixed package is available at [1]. If you can
   confirm that this brings us back to the 1.0.8-1 behavior, I'll
   prepare an upload with that fix.
