OK, so I couldn't resist a little play :-)

Seemed to work well with all the '.ly' files I threw at it. I generated 
PDF, PNG and MIDI files successfully. I tried a few files from a web 
site with lots of freely available lilypond files, and a couple of files 
gave warnings. If you try:

     wget 
http://www.mutopiaproject.org/ftp/PaganiniN/O1/Caprice_23/Caprice_23.ly
     lilypond --formats=pdf,png Caprice_23.ly

Then you see repeated instances of the following warnings:

     warning: no PostScript font name for font 
`/usr/share/fonts/100dpi/ncenR24.pcf.gz'
     warning: FreeType face has no PostScript font name

     programming error: Improbable offset for stencil: -inf staff space
     Setting to zero.
     continuing, cross fingers

I didn't have time to cross my fingers, but the resulting output files 
all looked fine ;-)

I ran the same test using the stock 'lilypond' package in Fedora 21 (the 
version of lilypond is the same), and the warnings weren't generated. 
The first warning is a little baffling, as lilypond knows where the 
PostScript fonts are (the path is specified as a ./configure option). 
It's worth saying that most of the files I tried worked fine without 
generating warnings.

BTW, I assume you're aware that the 'lilypond-doc' package is missing 
most of its content, and that this will be fully populated when the 
'corner case' you mentioned is ironed out.

Have you tried the old version of lilypond we have in x86 at the moment? 
I couldn't get it to work at all. Every '.ly' file I passed to it (even 
simple ones) caused a segmentation fault. So your suspicion about one of 
the dependencies looks well founded.

Dave.
