1) Create a new score for two flutes
2) First staff: Enter a D half note in first measure, and ditto in second measure
3) Second staff: Enter a chord: two tied D+A, eg in quarter notes

- See the test file at this step: Flute.mscz

4) Cut the second tied D quarter note (image below)

5) Copy-past this first measure second staff, in first measure first staff
You receive:

6) Undo
7) Note input mode "N"
8) Enter two notes eg two E

Result: crash

- No problem of course if there is no chord. Test file in this configuration: Flute1.mscz

Title Crash after undo on a deleted/copied-pasted note belonging to a chord ⇒ Crash after undo on a tied deleted/copied-pasted note belonging to a chord

I'm investigating. Second semester 2014 for sure for the moment ...
