Application: dolphin (25.08.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.2
Frameworks Version: 6.17.0
Operating System: Linux 6.16.7-200.fc42.aarch64 aarch64

-- Information about the crash:
Dolphin crashes when selecting an auto-discovered Windows SMB share.

Replication
1. Open Dolphin
2. Go to Network -> Shared Folders (SMB)
3. Try and select a server that's autodiscovered (in my case smb://arm-dev-pc.kio-discovery-wsd/)
4. Dolphin crashes.

The crash can be reproduced sometimes.

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


warning: Can't open file /memfd:wayland-shm (deleted) during file-backed mapping note processing
