Bug 431739

Application: dolphin (20.12.1)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.6.15-arch1-1 x86_64
Windowing system: X11
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:
A few weeks ago I did backup of my personal data stored in the damaged hard disk of my laptop by copying it to a Samba share located in
an EXT4 partition present in one of 3 hard disks available on my desktop computer. Today I tried to move some files and folders of my backup to another folder persent in the same partition where my Samba share is located, Dolphin shown a dialog about persmision failure, then I clicked on its "retry" button, Dolphin shown another dialog saying that the same file was not found, I clicked on its "Skip all" button and then Dolphin crashed. Nautilus file manager installed on the same system was able to move the same data to the same location without any permission issue or crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
