Adobe Reader needs a special object in the page for it to handle
included pdfs or pngs with transparency correctly on the first page
(search for pdftex and "page groups".) pdfTeX tries to fix this
automagically for years (1.40.6, I think) by synthesizing this object,
but Hans rejects any automagic solution for LuaTeX (since it may
conflict with mechanisms of ConTeXt) and ConTeXt instead tries to do
the right thing. Here it obviously fails.
