garbled-color image produced by pdftohtml

pdftohtml version 0.18.4 from Kubuntu 12.04 beta amd64.

I downloaded the 14MB PDF at http://www.swanyretail.com/SwanySkiCatalog_final-LO.pdf and ran it through pdftohtml with no options.
All the resulting jpegs are the right size but have garbled colors. They look like "solarized" negatives: mostly black, little color. 

To reproduce the problem,
  mkdir bugtemp
  cd bugtemp
  wget http://www.swanyretail.com/SwanySkiCatalog_final-LO.pdf
  pdftohtml -f 1 -l 3 SwanySkiCatalog_final-LO.pdf swany.html'
to convert just the first three pages.  Then look at the resulting swanys.html and/or the individual jpegs.

Here's the first bad image in the original PDF:

I'm guessing, perhaps pdftohtml doesn't handle ColorSpace DeviceCMYK ?

pdfimages extracts these as .ppm files that preview fine in Gwenview. pdfimages' -j option does nothing.

I'll attach the bad jpeg from pdftohtml and the good ppm from pdfimages, and pages 1-3 extracted with pdfseparate/pdfunite
