I fixed my problem by doing "chown -R apache:apache data/cache", the redoing the "moin ... cleancache". The fedora package update seems to have resulted in the cache/__common__/i18n directory being owned by root, which caused the cache read/write code in i18n/__init__.py to fail. I would have found this easier to debug if the cache read/write code had logged some errors due to the permissions problem.
