I can't really tell whether your file is too complex for musicxml2ly because I 
haven't seen it.  Probably not. Negative skips are an indication of 
time-related problems.  Quite a few programs export faulty pickup measures.  In 
some cases musicxml2ly has problems with certain ways of encoding multiple 
voices.  That's why I asked.  The Python error you posted might just disappear 
when you get a grip on the negative skips.  So the best (but tedious) way to go 
would be to open the .xml-file with a text editor take out (comment out or cut) 
all the measures but the first, run musicxml2ly (and lilypond) and see what 
happens.  If there are no errors and the compilation is successful paste in 
measure by measure and repeat the conversion and compilation until the first 
negative skip appears.  There is no easy way out if you want to help to improve 
musicxml2ly!

Give it a try.  If all else fails post me the file off-list.
