Bug 434435

Application: dolphin (20.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.4.0-66-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.2
Distribution: KDE neon User Edition 5.21

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

i use to connect to work servers with dolphin via the fish protocol, and Dolphin often crashes after few directory changes,and/or folder-tree opening/collapse.

The reporter is unsure if this crash is reproducible.

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