Because musicxml2ly couldn't properly handle breve and longa notes 
(double-whole and quadruple-whole notes)... I've now fixed this in git, so it 
should be in one of the next 2.11.x releases.

Apparently you are really pushing musicxml2ly to its limit in so many aspects! 
Thanks a lot for this, without you I would have never encountered a lot of 
the problems that you detect.

BTW, the problem with the "infinite loop" is that by default lilypond uses the 
minidom XML parser, which is apparently not very efficient for really large 
files (like yours) and can't handle them properly. There is the --lxml option 
to musicxml2ly, which causes musicxml2ly to use the lxml.etree XML parser 
instead, which is much more memory-efficient and is able to handle your file, 
but which is unfortunately not distributed with python but available as a 
third-party add-on.
I don't know anything about the advantages of minidom over etree (except that 
minidom is included in the python distribution, while lxml.etree is a 
separate module and needs to be installed separately), so I can't really 
judge wheter it would be better to use lxml by default...

Cheers,
Reinhold
