segfault with new fonts

[Graham Percival]

Hi Carl,

Could you do a make clean, then a make, followed by trying to compile this:

\include "../lilypond/Documentation/included/font-table.ly"
\markuplines \override-lines #'(word-space . 4)
             \doc-chars #shape-note-noteheads

I get a segfault; this is a slimmed-down version of the font-table NR
appendix.  Remember that "make" doesn't register any changes to fonts,
so checking with "make / make doc" alone isn't sufficient to test any
font changes.

Cheers,
- Graham
