It's :name "/red" as it's a pdf name.

With the / added you get a blank page so there is some progress ;-)
I think there is probably something missing in the XObject dictionnaries.
Maybe something to tell that it's a pdf file (a /ProcSet [ /PDF /Text ] ?)

You can also probably embed the content of the linked pdf into the master
one. This is even more interesting I think.
You should try to find or generate (with pdftex for instance ?) some pdf
with an embedded pdf  to see what is missing. (I had a quick look at the pdf
ref but it's not obvoius)
