Crash on importing MusicXML
Trying to open MusicXML files, I experience multiple crashes. One is with an empty file, with no content. MuseScore complains that "Element part-list is missing child element." , which is OK, but if I answer "Yes" to the question "Do you want to try to load this file anyway", MuseScore crashes.
If I try to open another file with content, it opens without questions or problems. But then, if I select the whole content, either by clicking in the first measure and shift-clicking in the last one, or clicking in the first measure and typing Ctrl+Shift+end, MuseScore crashes.
If I select progressively, clicking in the first measure, then Shift-clicking every five or six measures, I can succeed in selecting the whole staff and copying it. After that, selection works normally. (I can deselect and reselect directly from first to last measure.) Not sure whether this is due to my configuration or a more general problem.
