New crash information added by DrKonqi

dolphin (19.12.3) using Qt 5.12.8

- What I was doing when the application crashed:
Establishing general smb connection with a Win10 host on the local LAN.
It has previously established share folders using Netbios/Windows Network protocol that are visible to other Linux clients within the network.
Upon providing Windows user credentials, Dolphin abruptly crashes with no explanation.
This behavior is reproducible exactly.
Dolphin is connecting fine with other smb Win10 shares on the same LAN.

Comment 2 Harald Sitter 2020-08-31 10:31:07 UTC 
Moving to KIO. That's where it crashes.

Unfortunately the backtraces are missing context on the most relevant frames. Please have a look on how to improve them:
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Given the involved software versions are profoundly out of date I'm rather thinking this may have been long resolved.
