--------------------------+-----------------
 The `WP_Customize_Widgets::call_widget_update()` return a `WP_Error`
 instance when an error occurs. The instances are created with codes and
 not messages. However, when the `update-widget` Ajax request encounters
 this error, it then sends back the error info incorrectly by sending the
 message, when it is blank, and the code should be sent instead.

 Introduced in r31370.
