Possible bug: grace note/piano staff/repeat

[Knute Snortum]

I may have found a bug in LilyPond 2.18.2 but since I'm new to typesetting I want to run it past the list first.

The problem is a grace note that is inside a repeat appears outside of it.  There seems to be four things that have to happen at once:

1. Multi staff (Piano Staff in my case).
2. Repeat
3. First note of one hand is a grace note
4. The other hand does not have a grace note.

Here is the shortest source file I could construct that illustrates the problem.  If I should be doing something differently, please tell me.

\version "2.18.2"

upper = \relative c' {

| c c c c

\repeat volta 2 {

| c4 c c c

|

}

}

lower = \relative c {

| c c c c

\repeat volta 2 {

| \acciaccatura d8 c4 c c c

|

}

}

\score {

\new PianoStaff <<

\new Staff {

\clef treble

\upper

}

\new Staff {

\clef bass

\lower

}

>>

}
