[Swfdec] youtube.com complains about old version on 64 bit ubuntu gutsy

[La Monte H.P. Yarroll]

I read on lwn.net that swfdec has support for watching youtube.com 
videos. Good work! I have not been able to get the Adobe 32-bit mozilla 
plugin working under 64-bit gutsy so I figured I'd give swfdec a go.

A quick search of the archives and bugzilla turns up nothing obviously 
similar to my problem.

Viewing this page:

    http://www.youtube.com/watch?v=82Opqy5mFZM&feature=related

I get this error:

    Hello, you either have JavaScript turned off or an old version of 
Adobe's Flash Player.

This seems like it ought to be something very simple to remedy. I 
believe this is the check which is failing:

	<script type="text/javascript">
		// <![CDATA[
		writeMoviePlayer("playerDiv");
		var to = new SWFObject("/version-check.swf", "checker", "0", "0", "0", "#FFFFFF");
		to.write("checkerDiv");
		// ]]>
	</script>

I built swfdec 0.5 and swfdec-mozilla 0.5.5 from source tarballs on 
Ubuntu Gutsy Gibbon.

My laptop is a lenovo T60p.
