Doc build segfault

[Colin Campbell]

Since yesterday, make doc is erroring on a segfault from 
Documentation/web/ly-examples/bach-schenker.ly although the .ly compiles 
fine if I load it into Frescobaldi.  If anyone else is having the 
problem, I'll raise an issue.  I deleted ~/lilypond-git then git init 
and git clone, then autogen.sh -- noconfigure, cd build (already present 
from the clone), ../configure , make && make doc.  Came back after my 
show to find:
> GNU LilyPond 2.13.61
