Seems I am having more info about the offending images. If I try to run
jpeg2ps on one of the problematic jpeg images I get

$ jpeg2ps kk-000.jpg > kk.eps
Warning: JPEG file uses compression method C2 - proceeding anyway.
PostScript output does not work on all PS interpreters!

If I rebuild the pdf file after processing the jpg with imagemagick's

$ convert kk-000.jpg kk-001.jpg

problem seems to go away. So, this is apparently related to jpeg
compression method.

pstopdf filter is no longer available, so this no longer works. But at
least I know now why it was useful.
