minimum steps to reproduce:

Create a score with 3 staves

Title Copying and pasting invisible staff leads to crash ⇒ Copying an empty measure leads to crash

As I continued my testing I discovered that copying and pasting any empty measure will lead to the crash. Since the invisible staves are empty, they are causing the crash.

I tested with filled measures on either side of the empty measure (has a measure rest in it) and with an isolated measure rest. If you change the rest (like 2 quarter rests and a half rest in 4/4), the crash will no longer happen.
