musicxml2ly produces unexpected EOF in .ly file

[Victor Rouanet]

Good morning,

I'm having an issue with musicxml2ly, installed with a manually 
downloaded version on lilypond 2.19.82.

I exported a musicxml file from Musescore, then converted it to lilypond 
source with musicxml2ly without error. However, when I try to compile it 
with lilypond, I get the following error: "syntax error, unexpected end 
of input, expecting \header". Here is the full output: 
https://hastebin.com/raw/navufewufu

And the musicxml file content: https://hastebin.com/jafanosumu.xml

This error happened with any musicxml file I tried to convert from 
Musescore.

After some research, I found this topic on the lilypond-user list 
http://lilypond.1069038.n5.nabble.com/XML-to-ly-and-Lilypond-again-td203101.html 
which looks like exactly the same.
The suggested workaround (replacing 
split_string_and_preserve_doublequoted_substrings by string.split in 
musicexp.py:139) makes it work, but I'm wondering if I'm doing something 
wrong.
