Comment (by SergeyBiryukov):

 Works in [20267], broken literally 10 minutes later in [20268].

 If parent theme doesn't exist yet, `WP_Theme` constructor bails in line
 256, before `$this->parent` is set: [[BR]]
 http://core.trac.wordpress.org/browser/tags/3.4.2/wp-includes/class-wp-
 theme.php#L241

 `check_parent_theme_filter()` then bails in line 683 due to
 `$theme_info->parent()` being empty: [[BR]]
