Application: dolphin (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-38-generic x86_64
Distribution: Linux Mint 18.3 Sylvia

-- Information about the crash:
This is reproducible on my end, but occurs more commonly when another folder is being copied while another one is being duplicated as well; this is especially so when two copy operations are occurring, one of them finishes, then another folder copying operation is added to the file operation queue.

- What I was doing when the application crashed:
Copying folders from one device to anoher
- Custom settings of the application:
Hidden files and folders are shown

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
