Bug forwarded from Evince: https://bugzilla.gnome.org/show_bug.cgi?id=607780

"Hi,
  I cannot see some text in pdf files were fonts were embedded after the pdf
creation.


How to replicate:

echo "50 600 moveto /Courier findfont 30 scalefont setfont (the quick brown
fox) show" | ps2pdf - test.pdf


embed fonts using Enfocus PitStop Server 9


opne with xpdf ----> ok
open with evince --> fail
  Error: could not create type1 face
  some font thing failed

open with okular --> fail
  Error: Couldn't create a font for 'Courier'



I am attaching an archive containing:

test.pdf: fonts NOT embedded

test-p.pdf: fonts embedded by PitStop Server (evince cannot see text)

test-g.pdf: fonts embedded by ghostscript (evince sees the text)


Some info:

$ evince --version
GNOME Document Viewer 2.28.1

$ gs --version
8.70"

I can confirm FT_New_Memory_Face returns an error code (3, Invalid_File_Format). It works with xpdf that saves the font into a temp file, so I don't think the font is invalid. Acroread doesn't fail either. Maybe we are doing something wrong in GfxFont::readEmbFontFile() or it's a bug in freetype. 

Test cases can be found attached to the original bug report.
