musicxml2ly

I'm trying to convert a piece with musicxml2ly which was set and exported by MuseScore in musicxml. However it won't work, and this is the error log:Traceback (most recent call last):

ValueError: No closing quotation

I checked the xml with xmllint and it seems ok. The exported file is read back in MuseScore without problems, so it's probably a minor problem. Can musicxml2ly report on which line of the input file the problem occurs, so that I can have a look there? The XML file is 16 820 lines long.
