Qt Version: 5.5.1
Operating System: Linux 4.4.0-45-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I've unmounted an USB storage device, while dolphin still copied some files to that storage - I believe

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