partial measure with independent time signatures

[Peter Van Kranenburg]

Hello all,

Why isn't the \partial working in the code below?
I get:

/Users/pvk/tmp/polymeter.ly:20:3: warning: barcheck failed at: -1/8
d8
   | d4 f8 a
/Users/pvk/tmp/polymeter.ly:25:4: warning: barcheck failed at: 1/4
a,4
    | d4. e8 f4 g

If I include only one of the staves, everything is ok.

thanks in advance,
Peter van Kranenburg


\version "2.12.1"

\layout {
\context {
\Score
\remove "Timing_translator"
\remove "Default_bar_line_engraver"
}
\context {
\Staff
\consists "Timing_translator"
\consists "Default_bar_line_engraver"
}
}
% Now each staff has its own time signature.
\relative c' <<
\new Staff {
\time 2/4
\partial 8*1
d8 | d4 f8 a
}
\new Staff {
\time 2/2
\partial 4*1
a,4 | d4. e8 f4 g
}
