bug in 2.1.23

[Paul Scott]

I'm posting this realizing I might not be giving enough information to 
go on (since I have to leave for a performance in a number of minutes) 
in case it might help.

I am using Pedro's Debian packages and I have just converted some 
Lilypond files from 2.1.14 to 2.1.23 and I get this error:

paper output to `dy89wscore.tex'...
writing header field `title' to `dy89wscore.title'...
writing header field `subtitle' to `dy89wscore.subtitle'...
writing header field `piece' to `dy89wscore.piece'...

I will try to isolate this when I get back.

Thanks,
