Crash when creating parts if hairpin in Voice 2
version 3.1 beta / Windows 10 (and current nigthly ec75e63)
Weird problem by working on something else.
1) New score for two instruments, eg first piano staff and soprano (the test file: hairpin shortcut v2.mscz )
2) Enter four quarter notes in the first measure top staff in Voice2 necessarily
3) Select the second quarter note, and add a hairpin (no crash on the first beat), and necessarily with the shortcut "<".
(by selecting it, you notice this hairpin is highligthed in voice2, whereas if you enter it via the Lines palette, it is in voice1, even by selecting the second quarter note in voice2)
4) Create parts (new all -> Ok)
