Application: dolphin (20.12.1)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.4.0-62-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20

-- Information about the crash:
- What I was doing when the application crashed:
I had mapped to a local machine using fish:// and wanted to change the path from /"user"/home (I think it was /home) to
/snap

Tried twice and the same crash occurred,

Tried to also map just to fish://ipaddress/ and  it also crashed,

I haven't used fish:// before and mapping to root or another directory is probably outside the protocol? 

Anyway I don't consider this to be a critical bug - at least not in my use case.
 
- Custom settings of the application:

.None that i can think of - vanilla dolphin installation etc

The crash can be reproduced every time.

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