Error when using musicxml2ly - how to proceed ?

[Michael Gerdau]

Dear Lilyponder,

a couple of years ago I created a score in Sibelius that I now would
like to continue to work on with Lilypond. I thus have exported from
Sibelius (7.1.3) in MusicXML and tried to import in Lilypond using
musicxml2ly (2.19.26).

Unfortunately I get an error (see attached logfile).

How do I proceed ?

I've attached the compressed MusicXML as well but am happy to reduce
the size by removing stuff. However I have no experience in debugging
this sort of problem and would need a few hints as to what I should do.

The command invoked was
musicxml2ly --nd --nrp --no-beaming -m Machet\ die\ Thore\ weit.xml >Machet\
die\ Thore\ weit.log 2>&1

Kind regards,
Michael
