lyLuaTeX issues

[liebrecht]

I would appreciate if someone who understands the luatex compiler and 
lyluatex well to help with this.

It is clear that lyluatex is the future. It is already solving hordes of 
problems for me typesetiing music documents.
Unfortunately there is still a lot of work to do to get all or most 
Lilypond code to work with it.

As an example, a very helpful gent on this group "Mason" directed me to 
the public domain site  "http://lsr.di.unimi.it/LSR/html/whatsthis.html"; 
which contains great typesetting solutions.

I first check that the code I want to use there runs in Lilypond and it 
does correctly.

However when I copy the code over into
\begin{lilypond}
\end{lilypond}
and compile with lyluatex they about all choke the luatex compiler.
I am suspicipous of my TeXLive installation though, so if it compiles 
for you, it must be that.
TeXLive is really a step backwards in my opinion.

Anyway,

I attach an example file.
You can check that the lilypond section compiles correctly with 
lilypond.
It however fails with lyLuaTeX

Error:
