Bug 400858

Application: dolphin (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.15.0-38-generic x86_64
Distribution: Ubuntu 16.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Dolphin already opened with the location to save as one tab and another with a previous session where the dashcams were connected and both location where the dashcam files are to be saved (Front & Rear) and the same with the dashcams, so all I did to access the contents of each dashcam (I have 2) was to click on a clear part of the window for one dashcam and then the same for the other. Then I selected the files to copy from one dashcam then went to the location I want them copied then right clicked and sleected copy. A few minutes in is when dolphin crashed, there were quite a number of files and the duration was just over 1 hour to complete copy.

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