[wp-hackers] options capabilities bug?

This is a known issue, with a workaround added to 3.2. (You can see the
workaround in action in Twenty Eleven.)

Copying straight out of my own
I don't have to rewrite the explanation):

 * Filter Capability for Theme Settings Page
 * This filter implements a WordPress 3.2 fix for
 * a minor bug, in which add_theme_page() is passed
 * the "edit_theme_options" capability, but the
 * settings page form is passed through options.php,
 * which expects the "manage_options" capability.
 * The "edit_theme_options" capability is part of the
 * EDITOR user role, while "manage_options" is only
 * available to the ADMINISTRATOR role. So, users in
 * the EDITOR user role can access the Theme settings
 * page, but are unable actually to update/save the
 * Theme settings.
 * The function is hooked into a hook, introduced in
 * WordPress 3.2: "option_page_capability_{option_page}",
 * where {option_page} is the name of the options page,
 * as defined in the fourth argument of the call to
 * add_theme_page()
 * The function returns a string consisting of the
 * appropriate capability for saving Theme settings.
*function** oenology_get_settings_page_cap() {*
*	return 'edit_theme_options';*
*// Hook into option_page_capability_{option_page}*
*add_action**(** 'option_page_capability_oenology-settings',
'oenology_get_settings_page_cap' );*

I added on a bit to what Twenty Eleven does, by passing
oenology_get_settings_page_cap() to add_theme_page(), just to ensure

 * Setup the Theme Admin Settings Page
 * Add "Oenology Options" link to the "Appearance" menu
function oenology_add_theme_page() {
		// $page_title
		// Name displayed in HTML title tag
		'Oenology Options',
		// $menu_title
		// Name displayed in the Admin Menu
		'Oenology Options',
*		// $capability*
*		// User capability required to access page*
*		oenology_get_settings_page_cap(), *
		// $menu_slug
		// String to append to URL after "themes.php"
		// $callback
		// Function to define settings page markup

So, easy fix, once you know what's going on.
