Bug 428735

Application: dolphin (20.08.2)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.3-xanmod1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Doing anything on Dolphin (including nothing).
A freeze then appears after some time. If I wait about 30s or so, it usually becomes responsive again.
If I try to use it when it is freezing, it might end up crashing.

The crash can be reproduced every time.

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