  Target Milestone: ---

Application: dolphin (21.07.70)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.11.16-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.21.80
Distribution: "openSUSE Tumbleweed"

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

I was copying ~90GB of data from and to a NTFS formated internal HDD drive.

- Custom settings of the application:

I have tuned running using "latency-performance" profile as well as
vm.dirty_ratio=30
vm.dirty_background_ratio=15, otherwise i get hit with plasma getting slow as 
a turtle carrying the weight of the world.

The crash can be reproduced sometimes.

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