Crash on pasting trill lines with accidental
Here are the steps to reproduce, given you have created any score (no unpitched percussion)
1) Enter any note on your instrument
2) Put a trill line over it
3) Set an accidental on the trill line
4) Copy the trill line with the accidental
5) Paste anywhere
The program will crash upon pasting.
Using my attached "HAZMAT" score:
1) Copy one of the trill lines
2) Paste anywhere
The program will crash.
