Please read the notation reference, NR 1.2.6 Special rhythmic concerns

  Grace note synchronization can also lead to surprises. Staff notation,
  such as key signatures, bar lines, etc., are also synchronized.
  Take care when you mix staves with grace notes and staves without.
  This can be remedied by inserting grace skips of the corresponding
  durations in the other staves.

In your case

  \new PianoStaff <<
    \new Staff {
      \time 3/4
      \grace d''8 c''
    }
    \new Staff {
      \time 3/4
      \grace s8 r4
    }

Grace synchronization is tracked as issue #34
