Seems there's some akonadi + mysql-5.1.43 badness, so I'd recommend staying away from it for now. In short, initializing an akonadi database using 5.1.43 fails. Existing akonadi db's created with earlier mysql's seem fine. See also, "mysql-5.1.43 incompat with akonadi" https://bugzilla.redhat.com/566547 and mysql-5.1.43-1 bodhi updates: https://admin.fedoraproject.org/updates/F11/FEDORA-2010-1909 https://admin.fedoraproject.org/updates/F12/FEDORA-2010-1934 I've only been able to confirm this myself on F-12 (don't have any F-11 installs handy at the moment). -- Rex
