In your pdf file, descendant of font F3 (named ArialNarrow-Bold) is of type CIDFontType2, but its FontDescriptor has a key "FontFile" (you can check by opening your file in a text editor, and looking near lines 915 and 960)
According to pdf reference[1], FontFile should only be used with Type1. GfxFont::readFontDescriptor (in xpdf/GfxFont.cc:165) checks if FontFile is defined. If yes, and if type is not fontType1, it assumes, type is wrong (this is first error reason) and sets it to fontType1. Class of font objects is either Gfx8BitFont or GfxCIDFont, depending on type. So, at the end of GfxCIDFont constructor, you have a font object whose type is fontType1 In SplashOutputDev::doUpdateFont (xpdf/SplashOutputDev.cc:963) as fontType is fontType1, there is ((Gfx8BitFont *)gfxFont)->getEncoding() (on line 1084). I don't understand the technical details here, but anyway, you crash soon after. I attach a patch that seems to fix the problem. arno [1]: http://www.adobe.com/devnet/acrobat/pdfs/pdf_reference_1-7.pdf chap 5.8
