Bug 454133

Application: dolphin (21.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.17.8-200.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
1. Selected about 100 local images and copy them to the clipboard.
2. Navigated to the SMB1 share and paste files into share.
3. Files start copying.
4. Dolphin crashes.

I then reopen Dolphin and copy the files again to the same share, this time overwriting duplicates and Dolphin does not crash.
Other instances I can copy the files without Dolphin crashing. 
This behavior has further cemented that one should never move files but copy then delete the original once a succesful copy completes.

The crash can be reproduced sometimes.

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