Comment 16 for bug 170225

@~suv - The image in your document uses href directly, and not xlink;href as expected. Thus the issues is not due to an incorrect pathname handling (it works if you use xlink;href with the same path) but triggered by a missing NULL pointer test (needed when there's no xlink:href attribute at all). Now it's fixed locally (I'll send a new patch later, hopefully with other fixes).
