crash during musicxml2ly

[Frédéric Gohier]

hello,

I face a crash when run the command line :
/usr/local/bin/musicxml2ly --nd --nrp --npl --no-beaming -m 
MusicXMLV2_from_sibelius7.xml

the traceback is :
Traceback (most recent call last):
  File "/usr/local/bin/musicxml2ly", line 3277, in <module>
    main()
  File "/usr/local/bin/musicxml2ly", line 3271, in main
    voices = convert(filename, options)
  File "/usr/local/bin/musicxml2ly", line 3157, in convert
    update_score_setup(score, part_list, voices, parts)
  File "/usr/local/bin/musicxml2ly", line 3027, in update_score_setup
    score_structure.set_part_information(part_id, staves_info)
  File "/usr/local/share/lilypond/2.21.0/python/musicexp.py", line 2351, in 
set_part_information
    self.contents.set_part_information (part_id, staves_info)
  File "/usr/local/share/lilypond/2.21.0/python/musicexp.py", line 2135, in 
set_part_information
    c.set_part_information (part_name, staves_info)
AttributeError: PartGroupInfo instance has no attribute 'set_part_information'

I correct this issue by modifying

  *   in file git/python/musicexp.py :
  *   in class StaffGroup :
  *   in function set_part_information :

    def set_part_information (self, part_name, staves_info):
        if part_name == self.id:
            self.part_information = staves_info
        else:
            for c in self.children:
+                if hasattr(c, 'set_part_information'):
+                    c.set_part_information (part_name, staves_info)
-                c.set_part_information (part_name, staves_info)


I don't know the process to validate and don't remember the process to push a 
modification on git server.
please can you help me ?
