Bug 380402

Application: dolphin (17.04.1)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.68-2-default x86_64
Distribution: "openSUSE Leap 42.3 Beta"

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

Every time I click on the close button in the top right corner of Dolphin it crashes and shows a segmentation fault. It also crashes when I use File ->Quit and CTRL+Q.

The crash can be reproduced every time.

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