Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-31-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

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

Copied a file on an NFSv3 server.  From NFS location to the same export.  NFS server has root squash.

- Custom settings of the application:

NFSv3 storage (Solaris/ZFS/NFSv3), root squash, mounted on local system.  All Dolphin file copies done as a non-root user locally.

The crash can be reproduced every time.

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