Dia webpage, Firefox, and embedded SVG

[Javier Mora <cousteaulecommandant gmail com>]

So I was browsing http://projects.gnome.org/dia/python.html and got a 
message about a "missing (SVG) plugin":
    http://img221.imageshack.us/img221/6884/pantallazodiapythonplug.png
so I had a look at the page source code:
    http://img404.imageshack.us/img404/5171/diasourcecode.png
in other words, trying to make the page compatible with an old, 
uncompliant browser makes it fail with Firefox 11.  To top this, I'm 
suggested to "change" to Firefox.  Could someone please fix this?  (Or 
is it just my browser, and the page works ok for someone else?)

P.S.:  I'm not in the mailing list, but I'll try to check the archive 
periodically.

P.S.2:  Modern Firefoxes support embedding svg images as <img> tags  
(but old ones don't).
