Crash on open MusicXML file lacking time signature
1) Try to Open the attached file (open command)
2) Crash will happen immediately
The XML file seems to be well-formed. It was one among several I produced using an application called PlayScore. This is the only one that failed. So it may contain some element that provokes an exception from which the program does not recover gradually.
I retried regeneting the XML file from the application and repeating the action.. but it always leads to crash.
