Bug 387842

Application: dolphin (17.08.1)

Qt Version: 5.9.2
Frameworks Version: 5.40.0
Operating System: Linux 4.13.16-302.fc27.x86_64 x86_64
Distribution: "Fedora release 27 (Twenty Seven)"

-- Information about the crash:
- What I was doing when the application crashed:
I was moving a large directory from one partition to another, maybe I hit ctrl+z after finishing copying, but I think dolphin crashed when it was creating the 2000+ nested directories to move the files.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
