Lilypond 2.10.20 doesn't produce valid EPS with ChordNames

[Henry Flurry]

On MacOSX 10.4.9, Lilypond 2.10.20, the 
following fails to produce what OS X or 
NeoOffice (OpenOffice) thinks is a valid EPS:

============
\include "lilypond-book-preamble.ly"

{
\new ChordNames \chordmode { c1 }
}
============

It will produce a valid PNG

Other lilypond score files without 
ChordNames will produce a valid EPS.

Here is the compilation command used:

For EPS:

lilypond -b eps -feps test.ly > test.eps

For PNG:

lilypond -b eps -fpng -dresolution=300 test.ly > test.png

NOTE: this problem was originally discovered 
with the OOoLilyPond macro in NeoOffice.  
The image that NeoOffice would display from 
the generated EPS would simply contain the 
Title: and Creator: fields of the EPS.
