fatal error on MetronomeMark font-name override

[Kieren MacMillan]

Hello all,

In 2.19.30, the snippet

%%%%  SNIPPET BEGINS
\version "2.19.30"

\score {
  { \tempo "Tempo Test" c''1 }
  \layout {
    \context {
      \Score
      \override MetronomeMark.font-name = #"Century Schoolbook"
    }
  }
}
%%%%  SNIPPET ENDS

leads [on my computer] to the error

    warning: `(fondu -force /Library/Fonts/Century Schoolbook)' failed (256)

Any hints as to what I can do to fix this would be appreciated.

Alternatively, a simple way to un-bold the MetronomeMark (without using custom 
functions, etc.) would be sufficient for my current purpose.

Thanks,
Kieren.
