> I tried decoding the embedded base64 SVG, and batik rasterized it correctly.
> Here it is: https://dl.dropboxusercontent.com/u/73774/svg/inner.svg
> I tried inspecting the issue a bit, and the problem seems to be that the URLs in the embedded SVG that are in the form {{url(#SVGID_6_)}} are transformed to the form {{data:,#SVGID_6_}} which seems to cause the problem.
