Application: dolphin (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-26-generic x86_64
Distribution: Ubuntu 16.10

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

I was dragging multiple folders (less than 10) to another tab in dolphin with the intention to create symlinks to these folders, and upon choosing the option to create the links Dolphin crashed.
This does not happen every time, I have not yet determined what it is exactly that causes this procedure to crash dolphin.

Hopefully the backtrace (which to me reads as Chinese :-) ) can be more helpful than I am.

The crash can be reproduced sometimes.

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