"Programming error" message

[Tim McNamara]

Here's the programming error I mentioned in my other post.  It is  
repeated about seven or eight times:

programming error: FT_Get_Glyph_Name () error: invalid argument
continuing, cross fingers
programming error: Glyph has no name, but font supports glyph naming.
Skipping glyph U+FFFFFFFF, file /Applications/LilyPond.app/Contents/ 
Resources/share/lilypond/current/fonts/otf/CenturySchL-Roma.otf
continuing, cross fingers

The output seems to be unaffected and there is nothing missing from  
the printed score.
