Problematic pdf

The attached document apparently has some problems with the embedded Type 1C
fonts in it.  With gs 9.02, it reports errors and replaces the problematic
fonts with system fonts:

$ pdf2ps NovopashinMuriel2002_IsTheCriticalReynoldsNumberUniversal.pdf 
   **** Warning: can't process font stream, loading font by the name.
   **** Warning: can't process font stream, loading font by the name.

   **** This file had errors that were repaired or ignored.

   **** >>>> Mac OS X 10.6.7 Quartz PDFContext <<<<
   **** Please notify the author of the software that produced this
   **** file that it does not conform to Adobe's published PDF
   **** specification.

gs directly also reports:

The poppler pdftops output when printed produces the following error on the
printer:

ERROR: invalidfont
OFFENDING COMMAND: definefont

STACK:

/Font
-dictionary-
/RDNCVK+RusTimes-Pandre-LightItalic

It would be great if poppler could detect the same issue and do the same font
substitution.
