Comment (by westonruter):

 Replying to [comment:8 needle]:
 > I have encountered a fatal error in
 `WP_Customize_Widgets->customize_register()` when opening the Theme
 Customizer. This was after switching to a theme that has only one (empty)
 widget area. I confirmed that `$sidebars_widgets` in
 `wp_get_sidebars_widgets()` is not set, which throws the error when
 customize_register() tries to include the result in an `array_merge()`.

 Strange, because `wp_get_sidebars_widgets()` is supplying `array()` as the
 default fallback value if the `sidebars_widgets` option has not been
 added:

 {{{
 $sidebars_widgets = get_option('sidebars_widgets', array());
 }}}

 So it shouldn't be returning anything other than an array. What does
 `$sidebars_widgets` get set to in your environment?
