Description
register_setting() in wp-admin/includes/plugin.php adds a filter for each option registered. When this filter is later run by the sanitize_option() function the variables $value and $option are specified as arguments for the callback function. Since number of arguments ($accepted_args) was not specified when adding the filter in register_setting(), the $option argument is not supplied to the callback function.
This is simply fixed by supplying the $accepted_args argument to add_filter() in register_setting() and remove_filter() in unregister_setting().

Note:
See TracTickets
for help on using tickets.
For some context: supplying the $option value to callback functions is desirable since it will allow plugin developers to use a single sanitize function for all of the settings, instead of a single function for each setting.
