My girlfriend just made all these images for the clipart library by tracing them in Inkscape (rock!) and then editing and composing them with Adobe Illustrator CS. However, they cannot be opened in Inkscape.
I'm writing this to let everyone know that there are about 10 images available at this link, http://openclipart.org/submissions.php, done by Linda Kim that would be good for testing interoperability of Adobe SVG and Inkscape.
I created a bug on this and a new category for import bugs. If this one fits your fancy, it should be easy to write a script to strip out what Inkscape doesn't support, as can be done by hand in a text editor. However, to get Inkscape to allow for various unsupported features, or compliant svg that we don't suppor yet, might be more difficult.

Also, if anyone needs more examples, I can get those created in Adobe Illustrator CS.
