I changed the

    <<
      \new Voice \voiceOne { \afterGrace fis4 \glissando a8 }
      \new Voice \voiceTwo { \stemUp a4 }
      \new Voice \voiceThree { \afterGrace dis4 \glissando fis8 }
    >>



to

    <<  \afterGrace dis'4 \glissando fis8 \\ \stemUp a,4 \\ \afterGrace
fis4 \glissando a8 >>

and I get the correct glissandoes but I also get a warning:

....warning: ignoring too many clashing note columns
    <
      a, fis' >4 < gis e' >
new file.ly:13:21: warning: ignoring too many clashing note columns
    <<  \afterGrace
                    dis'4 \glissando fis8 \\ \stemUp a,4 \\ \afterGrace
fis4 \glissando a8 >>

So it's something to do with that construction but I cannot tell you why.

If that helps?
