Crash in File.write

[radianttap]

I just got this crash report.

I assume it's this closure u in File.swift file

  private func write(_ text: String?) -> String? {
    if let str = text, !str.isEmpty {
      queue.async {
        if let data = (str + "\n").data(using: .utf8) {
          self.file?.write(data)
        }
      }
    }
    return text
  }

The docs say

This method raises fileHandleOperationException if the file descriptor is closed or isn’t valid, if the handle represents an unconnected pipe or socket endpoint, if there isn’t any free space on the file system, or if any other writing error occurs.

Any ideas how to fix this..?
