A good idea is to either mail the list or - even better - file a bug
in bugzilla instead of mailing me. That way chances are higher that
someone can help you. And as a bonus, if the problem is solved, it can
be googled. :)

I am guessing that it is a linking problem similar to bug 10829 [1] -
though that one is on FreeBSD. There are probably symbol clashes with
the JS functions.
The volume slider on Youtube not working is expected btw. Sound should
work nonetheless.

Nope, the Swfdec plugin in GStreamer has nothing to do with modern
Swfdec. It's still for the age-old version.

There's two possible ways to approach the problem. One is to try and
get the Swfdec people to figure out what's wrong. That'd involve
filing a bug in our bugtracker, attaching stack traces etc. That may
be nasty as none of us
uses Suse or 64bit.
The other is to get OpenSuse to include Swfdec. I haven't had any
contact to Suse packagers, so I don't know how they handle it.
Probably some way of filing a request in their bugtracker? That way
you'd get someone in the know to figure out the right way to build the
plugin. And you could probably just copy what they did for your 10.2
install.
