svg won't display in firefox

Is there something wrong with this code? The picture displays fine in Safari but Firefox开发者_开发知识库 doesn't display anything:

<div id="container"><img src="picture1.svg"/></div>

You need Firefox 4.0b6 or later for svg in img to work there, here's the bug if you're interested. Opera has supported svg-in-img since version 9.5.
