Hi all!
I'm trying to recreate the photography "vignetting" effect using a svg created in Illustrator but when I try to load it in setup() I receive the following error:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
    at processing.core.PShapeSVG$Gradient.<init>(PShapeSVG.java:1267)
    at processing.core.PShapeSVG$RadialGradient.<init>(PShapeSVG.java:1328)

    at processing.core.PApplet.loadShape(Unknown Source)

If I change the svg image, using other images that I've used before with success, I don't receive this error... any idea?

This is the content of the svg file:

1. <?xml version="1.0" encoding="utf-8"?>
   <!-- Generator: Adobe Illustrator 15.1.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->

   </radialGradient>
   <rect y="0" fill="url(#SVGID_1_)" width="141.732" height="141.733"/>
   </svg>
   

Thanks!
