Comment 2 Jiri Palecek 2025-06-03 12:53:55 UTC

Yes, I've seen this crash. This is caused by url of the ListJob changing from smb://name/ to smb://user@name/.

Comment 3 Jiri Palecek 2025-06-03 19:46:49 UTC

Actually after some investigation, it is because KCoreDirListerCache is COMPLETELY unprepared for double redirects.
