Step to reproduce:
1.Create linked two staff (like two linked flutes).
2.Input note and select the note staff below
3.apply shortcut key, move chord/rest to staff above
Or other way around;
Select the note staff above, apply move chord/rest to staff below
The scenario is not normal, this shortcut aim to apply for cross staff notation.
But still It should not crash.
