Stefan: note that the bug does not occur with Bitstream Vera Sans. It is not enough for the font to contain the ligature glyphs (which Vera does) -- it must include the appropriate OpenType tables telling the text renderer to use those ligatures in the appropriate places.
I haven't checked the Junicode font, so can't comment there.
