XML-RPC WordPress api setOption double escapes args — at Version 1

Description (last modified by SergeyBiryukov)

Parts of the xml-rpc wordpress api are not usable, as they doublequote strings. e.g. Munich's becomes Munich\\'s.

wp.setOptions($args) escpapes all args and calls update_option() which is then calling mysql_real_escape_string(), leading to a double escaping. To solve this options should not be escaped in wp-setOptions() function.

Here the callStack showing the 2nd escaping:

wp-includes/wp-db.php.wpdb->_real_escape:884
wp-includes/wp-db.php.wpdb->escape_by_ref:950	
wp-includes/wp-db.php.array_walk:0	
wp-includes/wp-db.php.wpdb->prepare:1003	
wp-includes/wp-db.php.wpdb->update:1365	
wp-includes/option.php.update_option:258
