svg output from version 2.13.12 cannot cope with numeric time signature

[Bernard Hurley]

Using Ubuntu Linux 9.10 and lilypond version 2.13.12, if I do:

        lilypond -dbackend=svg test.ly
        
where test.ly is:

\version "2.13.12"
{
  \time 3/4
  c'
}


I get the output:

GNU LilyPond 2.13.12
Processing `test.ly'

 Wrong type argument in position 1 (expecting Font_metric): "CharisSIL"

It works as expected without the "\time 3/4"
