Activate Genesis and Genesis Simple Sidebars. Go to the widgets screen. You'll find a sidebar called "_".
The issue is with how SS_SETTINGS_FIELD is instantiated. See admin.php:
add_option(SS_SETTINGS_FIELD, '__return_empty_array', '', 'yes');
That makes the value of the option actually be '__return_empty_array'. When this is later fetched with $info['name'], PHP converts this to $info[0], or the first character of the string, and you end up with _.
Patch (which won't work until the pageload following, since widgets_init runs before admin_init) —
