Comment 2 Bernhard Friedreich 2025-09-04 20:06:33 UTC

Only happens on samba "devices", not on shared folders.

smb://nas-daten.kio-discovery-wsd/ => crash
smb://admin@nas-daten.local/daten/ => OK

Also crashes when opening the url directly (not via favorites in sidebar) or when opening through smb://

Other smb devices work
