starting with multimeasure rest bug

[David Bobroff]

The following *.ly snippet: 

\version "2.5.24"

\score {
  \relative c {
    \set Score.skipBars = ##t
    R1*9
  }
}

Produces this console output:

Interpreting music... [1]
Preprocessing graphical objects... 
Calculating line breaks... 
programming error: Multi_measure_rest::get_rods (): I am not spanned!
continuing, cross fingers
[2]
Calculating page breaks...
Layout output to `test.ps'...
Converting to `test.pdf'...

And there is no multimeasure rest displayed when the score starts with a
multimeasure rest.  Subsequent multimueasure rests are fine -- even if
one is added immediatley after the first one.  This is with recent CVS
(ChangeLog 1.3560)
