Application: dolphin (15.12.3)

Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.4.0-31-generic x86_64
Distribution: Ubuntu 16.04 LTS

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

Dolphin crash when  I drag  a big .mkv file (11.6 GB) from a 3.0 usb pendrive to a home folder for copy it. It could only copy about 135 MB until failure. I repeat and works fine.

The crash can be reproduced sometimes.
