Tried the file under Windows with 8.70, 8.71 and HEAD, all work. 

Tried HEAD under Fedora with the x11, ppmraw and pdfwrite devices, all work.
The x11alpha device does give a 'rangecheck in run' error. I presume this is
the well known problem with x11alpha and transparency. Since the PDF file is
generated by Cairo it probably contains spurious transparency.

Yes, the 'image' object, presumably the logo at top right, is a Pattern which
draws an image, drawn inside a form with a transparency group. Indeed, to add
to the complexity, the page has a different transparency group etc.

I can't reproduce the problem with HEAD on Linux without using the x11alpha
device though, so possibly the problem Till sees has been fixed?
