create this shape using CSS3 - css

Question

I would like to create this shape using just css. I am pretty sure this can be done. But i am having trouble with gradients involved.
This shape will contain some text inside. Suggested html markup is:
<div class="container">
... more html contents...
</div>
A jsFiddle would be highly appreciated.
Thanks in advance.

Nearly there with this: http://jsfiddle.net/Grezzo/52zG7/
You only need one div (thanks to pseudo element), but I haven't "cut" the corner yet.
