Application: dolphin (18.04.1)

Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.13.0-41-generic x86_64
Distribution: KDE neon User Edition 5.12

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

I opened dolphin, then closed it.   A few seconds later a crashed message popped up stating that "dolphin closed unexpectedly"  - This is seems to happen every time I close dolphin.  It doesn't hinder my day to day work but it certainly is annoying.

The crash can be reproduced every time.

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