Closing based on the earlier comments: The issue has not been reproducible with cairo >= 1.10, and the latest Inkscape packages for Windows and Mac OS X (0.48.2) now include cairo 1.10.2.
Issue remains when importing old PDF files created by Inkscape with lower cairo versions and certain PDF files created by other applications -> see Bug #840625.
