PNG export and SVG rendering in browsers wrong for a group with filtered + unfiltered paths

[worms_x]

I have a group of 3 objects, 2 of them are filtered (barbed wire for one / ink bleed for the second), and one is not filtered.

When opened in Inkscape, the rendering is "correct".
See attachment tutu_bug.svg opened in Inkscape

When I export this group to PNG, I get tutu_bug.png, where it seems that the unfiltered path is rendered incorrectly. It turns grey instead of being white, as if it was filtered.

The same happens when I open the SVG in Opera 10.00 alpha, build 1345.

I forgot to mention that this is using

http://inkscape.modevia.com/win32/Inkscape21271-0905012139.7z

on a Windows XP system, and that a build from April 20th tested by verbalshadow gives the same result.

Just for the record, Firefox 3 renders the SVG correctly.

Heh, this is kinda surprising, can I see the screenshot on Firefox 3, which I don't have installed?

In my Firefox 3.5b4pre (from april 15th, 2009), the SVG is not rendered correctly, it has all these grey thingies too.

I assume (naturally) that the correct visual result is what Inkscape shows?

r10141 still shows the same render as tutu_bug.png. Firefox 4 shows same result as 3.5b4pre.

Personally I don't see any problem with the unfiltered object, only the barb-wire object changes drastically. Or am I missing something?
