dolphin logs. crashing and working.
SUMMARY
Dolphin crashes when accessing an SMB share using an unsupported protocol.
After a few retries, it may not crash.
STEPS TO REPRODUCE
1. Open Dolphin
2. In the address bar, enter smb://192.168.1.x/
3. Enter login credentials when prompted
4. Press Enter
5. Dolphin crashes (note: may not happen every time)
OBSERVED RESULT
Dolphin crashes with a core dump. Terminal output includes:
smbXcli_negprot_smb1_done: No compatible protocol selected by server.
kf.kio.core: Internal error: itemsInUse did not contain
QUrl("smb://[email protected]/")
kf.kio.core: Fatal Error: HUH? Lister ... is supposed to be listing, but has no
job!
zsh: IOT instruction (core dumped) dolphin
EXPECTED RESULT
Dolphin should handle the error gracefully and show a clear message such as:
"No compatible SMB protocol found."
It should not crash.
SOFTWARE/OS VERSIONS
Operating System: Manjaro Linux
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.0
Kernel Version: 6.14.6-2-MANJARO (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5700X3D
Memory: 31.3 GiB

ADDITIONAL INFORMATION
The crash seems to be triggered by SMB protocol negotiation failure with the
server.
KIO does not appear to handle this edge case correctly, leading to a crash
rather than a fallback or error message.
