Ok, so the font is not correctly formed, but it seems that freetype can still render it "just fine". Personally i think it would be much better if freetype would render the font (maybe even with a printf saying "broken font trying to continue") instead of "punishing" the person that received a PDF with that font in it by not rendering it. There's that old saying that one should be strict when writing a format but flexible when reading the same format for maximum usability.
