Bug 405685

Application: dolphin (18.12.3)

Qt Version: 5.12.0
Frameworks Version: 5.56.0
Operating System: Linux 4.15.0-46-generic x86_64
Distribution: KDE neon User Edition 5.15

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

	Copy many files and folders using dolphin's split mode from one USB disk to another.

- Unusual behavior I noticed:

	Dolphin applications crashes unexpectedly

- Custom settings of the application:

	USB hard disk connected their own USB's port.
	Using dolphin to make copy in split mode. I did copy and paste files.

	About my environment:
	Size: 64,8 GB / 11229 file, 1846 sub-folders

The crash can be reproduced every time.

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