Rest skipped in MIDI when music starts with it

[Martin Tarenskeen]

Hi,

When, using Lilypond 2.19.0, if my score starts with a rest, the resulting 
MIDI file does NOT start with a rest.

%minimal example
\score {
  \version "2.19.0"
  \relative c' {
    R1 | c d e f | R1 | f e d c |
  }
  \midi {}
}
%end of example

Result: The MIDI file starts without a rest in the first bar.
The rest in the 3rd bar behaves normally.

Is this a bug, or intentional?
