Application: dolphin (21.08.2)

Qt Version: 5.15.3
Frameworks Version: 5.87.0
Operating System: Linux 5.10.0-051000-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.2 [KCrashBackend]

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

when i open smb://fritz.box, which maps to the network share of a FritzBox with FRITZ!OS: 07.20, Dolphin very briefly shows the login-dialog for the share a then crashes.

This was working up until ~4 weeks ago. 

A normal CIFS-mount works, but snice a recent yupdate of the FrirtzOS SMB1.0 no longer works, where previosly *only* SMB1.0 worked (an Dolphin could no open the share at all). So the Fritzbox seems to have moved from SMB1.0 to a newer version recently.

The crash can be reproduced every time.

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