New crash information added by DrKonqi

dolphin (23.08.0) using Qt 5.15.10

Steps to reproduce:
1- Create two files, let's say "test1.txt" and "test2.txt".
2- Select "test1.txt", hit Ctrl+C and Ctrl+V.
3- Dolphin will ask what you want to call the new copy, type "test2.txt".
4- Dolphin will ask if you want to overwrite the file.
5- Overwrite it.
6- Dolphin crashes and no file operation is performed.
