I had the same problem and fixed it by persisting the value in the onSetInitialValue method. The javadoc says: "If restorePersistedValue is false, you should set the Preference value to defaultValue that is given (and possibly store to SharedPreferences if shouldPersist()<http://developer.android.com/reference/android/preference/Preference.html#shouldPersist%28%29>is true)." It's that second part that is required.
