I have not quite settled this issue (not try by now to reproduce from scratch, no sure to succeed because there is a few entangled things apparently), but I probably have made good progress.

There is an incredible bunch of ties in this file (I do not know how this file was entered in GP ... but that's another story)
See the pdf of this file: Photograph.pdf

So, I managed to isolate two measures where the problem occurs.

- Load this file: with arpeggio and capo indication: 1 with arpeggio.gpx
Pdf file: 1 with arpeggio.pdf

Result: crash

- Load this second file: without arpeggio and always with capo indication: 2 without arpeggio with capo.gpx
Pdf file: 2 without arpeggio with capo.pdf

Result: crash

- Load this third file: without arpeggio and deletion of capo indication: 3 without arpeggio and capo.gpx
Pdf file: 3 without arpeggio and capo.pdf

Result: okay

BUT, now: add an arpeggio eg on the first chord: select F # -> double-click on an arpeggio

Result: crash

- So, now:
1) export this file in XML format: 3 without arpeggio and capo.xml
You note this format fixes the crash when you add an arpeggio eg on the first chord
2) Create parts
3) View part

Result (don't know by now if it's really related in a manner or another): three unexpected "orphan" (or falses?) ties which begin at the middle of the first measure and extend to the end of the second measure.
