Bug 378462

Application: dolphin (16.12.3)

Qt Version: 5.7.1
Frameworks Version: 5.32.0
Operating System: Linux 4.8.0-46-generic x86_64
Distribution: KDE neon LTS User Edition 5.8

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

I had moved one file -dragging it between two open tabs-, from one folder to another in the same HD when crashed.
Había movido un archivo -arrastrando entre dos pestañas- desde una carpeta a otra del mismo disco duro cuando falló.

The crash can be reproduced sometimes.

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