BZ 473903 is unresolved for Fedora 11. Steps to reproduce: 1. Log in and fonts are the wrong size. 2. Open gnome-appearance-properties. 3. Fonts magically fix themselves for the remainder of the session. 4. Logout of session and log back in. 5. Font problem returns.
Is gnome-settings-daemon running in your session before you start gnome-appearance-properties ?
yes.
