This is yet another example where a particular glyph is simply missing from the output (look at the reftest images: the uppercase "A" in the reference file is missing, while all the other glyphs -- from the exact same font -- are fine). We've been seeing this symptom happening sporadically for months, on random testcases; see bug 1392106.
