Bug 409857

Application: dolphin (19.04.3)

Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 4.15.0-54-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:

I was working with an USB3 Flash Drive with a FAT32 Partition.
When trying to copy data from a SD-Card over I accidentally removed the Flash-Drive.
I tried to copy the rest of the data with skipping every file which is already on the drive.
After asking me if it should replace already existing files and me saying skip them and apply to every one of those dolphin crashed.

The crash can be reproduced every time.

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