Problematic PDF

Summary:
Converting PDF->PNG produces wrong colors in the final PNG. Using dUseCIEColor improves the result a bit (towards the right colors). Not using dUseCIEColor will produce colors that are completely off (purple for black, etc).

Expected result: 
http://goo.gl/nwxQW (flip to page 6)

Actual result: 
http://goo.gl/2ls3B

Command line:

-dUseCIEColor -dNumRenderingThreads=1 -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dAlignToPixels=0 -dGridFitTT=0 -dUseCropBox -r250

Attached is the original PDF.

Tried latest head revision (12309) which produces correct colors for this page. The bug has most likely been fixed.

However, using the newest head revision, another bug has shown up: http://bugs.ghostscript.com/show_bug.cgi?id=692098
