repro case

1. Open attached svgtest.html from SVGtoDataURLBug.zip
-or-
1. In JavaScript, Create a canvas element
2. use drawImage to draw a new Image() from an SVG source
3. call toDataURL() on the canvas

I would expect to get a data URL with png contents of the image.

Safari instead reports:
SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent.
