Misplaced grace note slur

[Helge Kruse]

I am writing a separate voice of cue notes. I think it looks wrong when 
a the slur in the acciatura is far away of the first note. Please look 
at the g in following example:

\version "2.16.0"

violin = \relative c'' {
  \key f \major
  \time 3/4
  c2~ c8 r |
  d4\pp( e \acciaccatura{g8}f4->) |
  e2. |
}

\score {
<<
    \new Staff \new CueVoice << \violin >>
    \new Staff << \violin >>
  %  \new PianoStaff ... with the harp voice ...
>>
}

How can this small slur get a similar position as in the normal context?

Regards
Helge
