Application: dolphin (17.12.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-23-generic x86_64
Distribution: Ubuntu 18.04 LTS

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

Moving a file from ~/Downloads to another directory - which at the moment I can only remember has been to a cifs mount at /<cifsmount> but may have happened again as I get this error every time (10+ times) since upgrading to Kubuntu 18.04. 

First the error states that there are permissions preventing writing to the folder, then after clicking retry, it says the original file is missing in ~/Downloads, hitting retry brings errors, and after clicking ignore, Dolphin crashes. Checking the destination folder, the file is there and was actually moved.

The crash can be reproduced every time.

-- Backtrace:
