This image can be uploaded as the PNG file that Inkscape creates from the "export bitmap" option, but the very SVG file that I edited with Inkscape is refused at page http://openclipart.org/media/file/add/15217 by OpenClipart.Org with the message in red "There was error in the file format
The file it won't allow me to upload is attached to this bug report.
Closing all openclipart bugs as openclipart is now on launchpad, as per request from Jon Philips.
