Bug 433551

Application: dolphin (20.08.2)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-44-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

-- Information about the crash:
- What I was doing when the application crashed: Switch view mode from tree to icons. Dolphin was in full screen mode displaying a directory tree struction with ownership and permissions, I was switching it back to normal (icons) view mode when the crash occured. The directory was on a local disk. No other foreground activities were running.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
