Bug description

Copy pasted a certain selection - program crashed

Steps to reproduce

1. Store this data in your clipboard (viewed using clipboard viewer)

MuseScore Version

Regression

I don't know

Operating system

macOS 12

Additional context

I copied from a selection in a project I was working on. Let me know if you want the project. Unfortunately I don't have that project saved when musescore crashes so I'm not sure if it still contained content that can trigger this bug.

@sclsj Please add more details to repro steps. What should be copied/pasted from this long txt file?

This should be written to the clipboard (pasteboard) under the key com.trolltech.anymime.application--musescore--stafflist.

Try this solution by GPT-4. It works on my machine.

TL;DR: compile this swift snippet swiftc -o copyToClipboard copyToClipboard.swift, and run it on the downloaded com.trolltech.anymime.application--musescore--stafflist.txt file:

import Cocoa

let filePath = CommandLine.arguments[1]
let customMimeType = "com.trolltech.anymime.application--musescore--stafflist"
let pasteboard = NSPasteboard.general

do {
    let fileContent = try String(contentsOfFile: filePath)
    pasteboard.declareTypes([NSPasteboard.PasteboardType(rawValue: customMimeType)], owner: nil)
    pasteboard.setString(fileContent, forType: NSPasteboard.PasteboardType(rawValue: customMimeType))
} catch {
    print("Failed to read the file or copy to clipboard: \(error)")
}
