Flat symbol in instrument header line?

[Toby Dylan Hocking]

To whom it may concern,

I recently have started using Lilypond to typeset music. Most functions 
seem to be straightforward and intuitive. Thanks for this great piece of 
free software. However, I have one problem, which I suspect is a bug.

I use the following segment in my input file:

\header{
        title = "Surfin' U.S.S.R."
        composer = "Toby Dylan Hocking"
        instrument = "Saxophone in E\flat"
}

I get the following messages at runtime:

GNU LilyPond 2.4.5
Processing `surfinussr-eflat.ly'
Parsing...
Interpreting music... [8][16][24][25]
Preprocessing graphical objects...
Calculating line breaks... [3][6][9][12][15][18][21][24][25]
Layout output to `surfinussr-eflat.tex'...
Converting to `surfinussr-eflat.dvi'...
Error invoking `latex \\nonstopmode \\input surfinussr-eflat.tex > 
/dev/null 2>&1 '. Return value 256
Converting to `surfinussr-eflat.ps'...
Converting to `surfinussr-eflat.pdf'...

There are two symptoms of the problem:

1. The "Error invoking..." runtime message

2. The output .pdf file is produced off center (see attached pdf)

I have figured out the problem is invoking `\flat' in the instrument 
line, because the problem goes away if I change it to `-flat'.

I am running Lilypond 2.4.5 on SunOS 5.8.

It seems that this must be a bug. If not, tell me what I am doing wrong 
and how I can typeset the flat symbol in the instrument header line.
