Written books given by commands will have * Invalid book tag * in it

What I expected to happen was...:
/give @p written_book 1 0 {display:

{Name:"Menu"}

,pages:["

{text:\"Menu (Click to activate):\n\n\n\"}

"]}
should give the player a book with text inside

What actually happened was...:
A command made in 14w25b will now just give a book with the text * Invalid book tag * in it.
All books given have this inside
/give @p minecraft:written_book
should be an empty book but it ll have the error in it
