Hmm. On further investigation this bug goes quite a ways back in the 2.7 
tree, with the introduction of the use of VerticalAxisGroup to set 
Y-extents for staves.  As I recall, Lilypond development went into 
"brain surgery" mode about this time, so deconstructing exactly what 
introduced this bug could be very hairy.

I hope this can be resolved soon, because otherwise I'm going to have to 
revert to 2.6.5 (or 2.7.12 for shape-note pieces).

P.S. For the sake of completeness, here is my system layout:

Gentoo Linux
Guile 1.8.0
AFPL Ghostscript 8.53 (with the global glyph names patch applied)
Python 2.4.2
Pango 1.12.1
Freetype 2.1.9
