and also with

\pdfximage{fig.pdf}\immediate\pdfrefximage\pdflastximage

but I am not sure that it is a bug. I think \immediate not expected to
precede \pdftrefximage, according to the following syntax description
extract:

  " The image is kept in memory and will be written to the PDF output
    only when its number is refered to by \pdfrefximage or \pdfximage is
    preceded by \immediate. Nothing is appended to the list being
    built. The number of the most recently created XObject image is
    accessible via \pdflastximage. "

In any case, pdftex 0.14h already behaved this way.

Regards,
Ricardo.
