Comment 8 for bug 1438494

Does this bug also occur if there are no embedded fonts in a pdf? Because my canon scanner seems to produce pdfs without embedded fonts, at least pdffonts shows no fonts:
$ pdffonts SCN_0002.pdf
name type encoding emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------

 and i get a very similar error when trying to minimize the filesize with ghostscript:

$ gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -sOutputFile=out.pdf SCN_0002.pdf

With the minimal gs version from http://www.ghostscript.com/download/gsdnld.html its working flawlessly.

i attached a pdf created by my scanner to this comment.
