Gradient stops positioning in clipped shape

[Stefano]

I am using this handcrafted SVG to test:
======
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<svg version="1.1"
     width="100"
     height="100"
     viewBox="0 0 100 100">

<linearGradient id="grad">
  <stop style="stop-color:#ff0000;" offset="0" />
  <stop style="stop-color:#ffffff;" offset="0.5" />
  <stop style="stop-color:#0000ff;" offset="1" />
</linearGradient>

<clipPath id="cp">
  <path d="M 0,0 50,0 50,50 0,50 z" />
</clipPath>
<rect style="fill: url(#grad);"
      width="100"
      height="100"
      x="0"
      y="0"
      clip-path="url(#cp)" />

</svg>
======

Basically there is a rectangle filled with a gradient that goes from left to right and from red to white to blue. Then I clip it to the left half.

I'd expect to see only the right half transparent, and the left half with a gradient from red to white (no blue). Eog shows it like that.

Inkscape shows the right half transparent (correct), but the gradient in the left part is re-positioned relative to the clipped region, so I see the whole gradient from red to white to blue.

I am not an expert on SVG spec, so it might be as well a problem in the library that eog uses, but eog's behavior seems more natural, so I tried reporting it here first.

I am using inkspace 0.48.5.

Attaching pasted SVG source as file to ease testing …

Attaching fixed version (missing root element namespace declaration).

On OS X 10.7.5:
- reproduced with Inkscape 0.48.5
- not reproduced with Inkscape 0.91pre2 r13666
- not reproduced with Inkscape 0.91+devel r13778

Will be fixed in the upcoming release 0.91.
