Inkscape doesn't render properly to PDF

[Muelli]

I tried to render http://www.bagu.org/gnome/officialdekthappy.svg to PDF, but it produces a PDF with blocks, and no proper smiley face.

SVG file to be rendered

FWIW: Firefox has the same issue.

Please add information about OS/platform and Inkscape version.
Which PDF viewer did you use to verify the content?

(Apple's preview renders your PDF file as expected, whereas evince 2.30.3 renders the strokes with gradients incorrectly, see attached screenshot).

The same incorrct rendering in evince occurs when Inkscape uses cairo 1.10.2 or cairo 1.11.2 (snapshot).

The same error happens when the svg file is converted to PDF using 'rsvg-convert' (from librsvg), which indicates that this is an upstream cairo or poppler bug and can't be addressed in Inkscape's code base.

Possibly same issue as reported in
Bug #543279 “Unfilled rectangle with gradient on stroke becomes filled in PDF”

PDF file generated with rsvg-convert (librsvg 2.34.0, cairo 1.10.2):

$ rsvg-convert 779969-officialdekthappy.svg -o 779969-officialdekthappy-rsvg.pdf -f pdf -x 0.8 -y 0.8

I'm using inkscape 0.48.0-1ubuntu1.2 with evince from maverick which uses libpoppler7-0.14.3-0ubuntu1.1

PDF looks ok in Evince after converted the strokes to path which use a gradient fill.
