bug: grace notes before double bar line

[Karol Majewski]

The bug occurs in 2.16.2 when using global section:

%%%%%%%%%%%%%%%%
\version "2.16.2"

global= {
  \time 4/4
  \key c \major
  s4*4 \bar "||"
  s4*4 \bar "|."
}

violinOne = \relative c'' {
  c1
  \grace f8 e1
}

violinTwo = \relative c'' {
  g2 f
  e1
}

\score {
  \new StaffGroup <<
    \new Staff << \global \violinOne >>
    \new Staff << \global \violinTwo >>
  >>
}
%%%%%%%%%%%%%%%%

I wonder if it happens in 2.17. Anyway....I need a quick workaround for
this... is it possible to shift this double bar line somehow?
