How exactly were you mounting the Samba share to make this happen? I clicked on a link added to Places panel, under Remote. kioworker also crashes after click on Shared Folders (SMB) icon inside Network section of the Places panel. There is a q_assert that breaks in kdsoap-ws-discovery-client :

Patrick Silva, do you have Ipv6 support on your network ?
ipv6 was disabled on my system. I have enabled it right now and the crash is no longer reproducible with double click on Shared Folders (SMB) icon inside Network section of the Places panel.

Committed on 18/03/2024 at 15:25. Pushed by sitter into branch 'master'. be more lenient with failing message submission warn when submission of both ip types fail and assert for debug builds. this allows either type to be disabled while still making it super obvious when something is broken in debug builds M +12 -8 src/wsdiscoveryclient.cpp https://invent.kde.org/libraries/kdsoap-ws-discovery-client/-/commit/14e0fb7658a9b21de1599c92337a102f9c9633e4 |
