juergen spitzmueller found a bug in sebastian rahtz's rotating package, which i now maintain. i have now mended the bug (which i introduced), and i have installed a new version of the package on ctan (note that a file rotating.tds.zip also exists, for the convenience of those who maintain their own systems).
users may visit the catalogue entry for the package at http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/rotating.html or browse the package directory on the archive at http://www.tex.ac.uk/tex-archive/macros/latex/contrib/rotating/
i have updated the catalogue entry in the repository, and the link above will be updated overnight, but is unlikely to deceive in any important way before then.
