Bug 435435

Application: dolphin (20.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.11-zen1-1-zen x86_64
Windowing System: X11
Drkonqi Version: 5.21.4
Distribution: "Arch Linux"

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

I opened Dolphin. I can successfully navigate folders and directories, but right clicking on any file or folder crashes Dolphin. I haven't made any significant changes, although I have recently updated my system (and subsequently rebooted) to latest Arch Linux repo packages. 

This crash appears to be caused by a Dolphin plugin I have installed: Trigger Syncthing Scan. Disabling all plugins fixes the crash, although enabling it alone reproduces it. (I believe this is added by syncthingtray, but I'm not sure).

Regardless, Dolphin plugins shouldn't cause a total application crash, so I'm still reporting the bug. (Unless this is intended/acceptable behavior: then this report might be useful to someone else, I guess.)

The crash can be reproduced every time.

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