Application: dolphin (20.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.0-8-amd64 x86_64
Windowing system: X11
Distribution: Debian GNU/Linux 11 (bullseye)

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

I navigated to a folder in the right pane, selected the folder name (with the branch collapsed), and just pressed Ctrl+C to copy the whole folder. 

- Unusual behavior I noticed:

I noticed 30 minutes or so earlier, but in the same Dolphin session, Dolphin was very busy, taking up 50% CPU utilisation for at least 15 minutes. This is an old, slow desktop but it was still excessive. Then, utilisation dropped to normal levels, below 5%.

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