The difference between the source SVG ( http://upload.wikimedia.org/wikipedia/commons/6/61/Two_hybrid_assay.svg ) and the PNG created by Wikimedia ( http://upload.wikimedia.org/wikipedia/commons/thumb/6/61/Two_hybrid_assay.svg/480px-Two_hybrid_assay.svg.png ) is visible in the capture of the light green rectangles. Whereas the SVG file says "Reporter gene (LacZ)", the converter outputs "Reporter gene() LacZ".
I see general font positioning issues with rsvg, we have plenty of bugs open on that. The (lacz) part is dupe of bugzilla 17174. *** This bug has been marked as a duplicate of bug 17174 ***
