Thanks to this bug report I was able to solve this issue on my system. I'd just
like to give additional details.

Firstly, here was the error message:

]# pdf2ps  doc-01.pdf test.ps

I knew ghostscript often has trouble with fonts, and doesnt seem to try a best
guess substitution, so I read between the lines that "Error: /undefined in
findresource" and "Arial" in the next line probably indicated a problem with
the Arial font. This made sense, as this is on a linux machine :)

So, I found an rpm of the ms core fonts. I found one here, but I know they can
be sourced all over the net:

ftp://ftp.gwdg.de/pub/linux/misc/suser-jengelh/AnyDistro/noarch/MicrosoftFonts-1-jen14.noarch.rpm

Then I edited /usr/share/ghostscript/8.71/Resource/Init/cidfmap.GS (fedora 14)
and added:

/Arial << /SubfontID 0 /CSI [(Artifex) (Unicode) 0] /Path
(/usr/share/fonts/truetype/arial.ttf) /FileType /TrueType >> ;

And the pdf converted successfully. Thanks those who helped with the fix.

Feature requests:

1) Could the error message be modified so that after the stack dump, something
like "Unable to find font Ariel, or fall back font Adobe-Identity" (that was
about the gist of it I think?).

2) Could ghostscript be modified to try harder to use a font of about the
expected size for the unknown font scenario by default, so rather than break, a
best-as-possible rendering is produced?

For reference, pdfinfo tells me this is the format of my source file:
