It was 0.991.

I've just tried it with zlib compressed (I always use this option) and the
problem is indeed fixed, so the PDF generated is now viewable with
macosx's preview.

While testing it I noticed that for the picture I tried (a scan of
a mostly blank letter-size yellow sheet in 150dpi and greyscale) I get the
following file sizes in bytes:

0.991: 1551241
0.994: 1211006
0.991 through pdf2ps|ps2pdf: 127159
0.994 through pdf2ps|ps2pdf: 127163

So the 0.994 version also generates smaller files (at least for this one
test).  Oddly enough pdf2ps|ps2pdf generates much smaller files still (my
experience has indeed been that it generates smaller files, but usually just
by maybe 10-20%, kind of like what we see between the 0.991 and 0.994 files,
so it seems this here test is not representative of my more usual scans ;-)

Thanks for fixing it without my even asking for it,
