 * It does not reproduce. What is your PHP version?

 * Are you using any custom post type?
 * Although it is speculation, it seems that a warning has occurred because you 
   accessed the array using type data (empty string) even though you can not get
   a custom post type.
 * I can not do it right away, but I would like to take some measures by the end
   of this month.

 * My theme has video, gallery and audio post beside the normal provided by WordPress
   so, if you’re talking about this with “custom post type” I would answer yes.
