It's a known issue ("Grace note synchronization"):
http://lilypond.org/doc/v2.16/Documentation/notation/special-rhythmic-concerns#index-grace_002dnote-synchronization

The workaround is using a grace with skip rests in the other staff:

left = \relative c   {
  \clef bass
  \key f \major
  \grace { s32*3 }
  f1
}

Here's the very old bug report:
