Crash reproducible on neon unstable. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.81.0 KDE Frameworks Version: 5.245.0 Qt Version: 6.6.0 Graphics Platform: X11
Confirmed with following steps 1. Create files to empty directory with bash oneliner: `for i in {1..5142}; do dd if=/dev/urandom bs=1024 count=100 of=test-${i}.jpg; done` 1.1. Warning, that will create 500mb worth of fake jpg files 2. Select all with ctrl+a 3. Rename with f2 4. Allow renaming to finish 5. Press ctrl+z 6. Press ctrl+q when the renaming process starts again 7. Crash! The files do not have to be jpg files, any files will do.

Git commit d807cbe0a7fb02ff6bda4f7be066c1323423743f by Akseli Lahtinen. Committed on 08/12/2023 at 13:25. Pushed by akselmo into branch 'master'. Fix crash if window is closed when undoing If dolphin is closed when undoing something, this will crash. Set parentWidget as QPointer to avoid crashing: Instead, the undo process gets cancelled gracefully.
