acciacatura at the beginning of a measure

[Victor S. Miller]

I'm using LP 2.2.6.  I found the following problem:

I have a vocal line which has an acciacatura at the beginning of a
measure, where I change time signature.  I find that when I typeset
this by itself it comes out just fine.  However, when I combine it
with the piano accompaniment, I get a time signature at beginning of
the measure, and then after the acciacatura.  Any suggestions for a
work-around?

Here's a file that provokes the problem:

\version "2.2.6"
V = \notes \relative c' {
    \key g \major
    \clef "G_8"
    \time 4/4
    \acciaccatura c64 d2. r8 g, | %9
}
T = \notes \relative c' {
    \key g \major
    \time 4/4
    \times 2/3 {
        d'4~ <d, d'>~ <d g d'>~

    <d g d'>2 | %9
}
B = \notes \relative c {
    \key g \major
    \time 4/4
    b1 | %9
}
\score {
    <<
        \context Voice = "A"
        {  \V }
        \context PianoStaff  <<
            \context Staff = "up" {
                \new Voice
                \T
            }
            \context Staff = "down" {
                \notes \clef bass
                \B
            }
        >>
    >>
    \paper { }
}
