lyrics and aftergrace

[Stefan Thomas]

Dear community,
I have a problem with lyrics and aftergrace.
In the following snippet, the lyrics don't align to the music as expected.
global = { \key d \major \time 6/8 }
melodie = \relative c'' { \global \afterGrace  cis2.\trill{ b16 [ cis] }  d4 }
text = \lyricmode { Lied im Grund. }

\version "2.12.0"

     \score {
        <<
           \new Voice = "eins" {
              \autoBeamOff
              \melodie
           }
           \new Lyrics \lyricsto "eins" \text
        >>
     }
