Description guimarcalsilva 2021-03-24 02:29:43 UTC

Application: dolphin (20.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.4.0-67-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.3
Distribution: KDE neon User Edition 5.21

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

By accident I discovered you can scroll on the name of a folder on the top navigation bar in order to quickly switch between directories. Well, out of curiosity I started doing that to check all folders in /usr/share/ and Dolphin crashed. It didn't crash at first, but it crashed when I was scrolling between different folders for some time. I tried doing the same to see if it would crash again and it did. I'm not sure if it's related to how fast I was switching folders or not (I was scrolling fast), but both times I had to keep scrolling for a minute or two before the crash happened.

The crash can be reproduced sometimes.

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