Comment 39 for bug 168244

Linking as duplicate to bug #171795, which is still open for all supported platforms (the commit referenced in comment 38 had been reverted, and even on linux current Inkscape (0.91, 0.91+devel r13904) uses the Gdk-pixbuf loader to rasterize an SVG image linked via <image> tag).

The packaging issue on OS X has been resolved (fixed in packages for Inkscape 0.48.5 and 0.91), the packaging problem with librsvg and its gdk-pixbuf loader on Windows is now tracked in bug #1271938 (template preview image is affected by the same issue).
