Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-62-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

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

After copying a file from a POSIX-compliant NFS share to an NTFS partition exported over NFS (which doesn't support permissions), Dolphin attempts to change permissions on the new file and crashes. The expected behavior would be to show the error message that permissions could not be changed, but to remain open. While this is certainly not a typical situation that would be encountered very often, the uncaught exception causing the program to crash is very disruptive and should be handled differently.

The crash can be reproduced every time.

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