Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-89-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

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

Copied some jpeg images to an sftp share. The share is a VFAT partition, so Dolphin first popped up a few "cannot change permission" dialogs, and then crashed with a segfault.

The crash can be reproduced sometimes.

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