Application: dolphin (16.12.3)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-26-generic x86_64
Distribution: Ubuntu 17.04

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

I had my smartphone connected via MTP to the PC, I was going to pass several .zip files to the smartphone. As it would not let me copy and paste I had to drag the files
The first .zip file I dragged moved perfectly, the error came when I moved the next two .zip files, suddenly Dolphin was closed, although in the notifications reported that the process was completed, it did not move the files properly. So I rebooted Dolphin.
I re-moved the files that Dolphin had wrongly moved and other new .zip files and the error did not happen again.

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