Application: dolphin (16.08.2)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.49-16-default x86_64
Distribution: "openSUSE Leap 42.2"

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

An NTFS drive is mounted on /mnt/E with fstab parameters:

    users,uid=root,gid=users,fmask=111,dmask=000,locale=zh_CN.UTF-8

therefore the files and directories are world writable.

When I move (not copy) a file from desktop or home to /mnt/E, the file is successfully written, but a dialog says (translated from zh_CN) "Access denied for /mnt/E/filename", with buttons "Retry", "Cancel", and "Skip", "Auto Skip" in case of multiple files.

If I click "Cancel" for one file, the dialog will disappear and the file is moved. However if I click "Retry", or click "Skip" for multiple files, dolphin will crash and may leave the destination file corrupted. 

Modifying the fstab parameter "uid=root" to "uid=myusername" can workaround the problem, but only useful for a single user.

The crash can be reproduced every time.
