Application: dolphin (17.12.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-66-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

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

I was moving files between two folders using the mouse in the split view. If you click a file twice within a long period the title can be edited. No problem there; normal operation as usual. The problem appears when you accidently double click the file that you want to move. Instead of moving the file itself, trying to accidently move the title ALWAYS crash Dolphin.

The crash can be reproduced every time.

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