SUMMARY

After updating to kio 6.19.0, I cannot copy or move files to my SMB share, or rename/move files within it, as it fails with "Access denied. Could not write to smb://hostname/path/to/dir/."

I bisected the issue to merge request https://invent.kde.org/frameworks/kio/-/merge_requests/1990 (commit 15fff1b8592648f11f20a303c8f82d61d3f19584). Downgrading the kio package to 6.18.0-1 or reverting the commit both fix the issue.

STEPS TO REPRODUCE
1. Copy a file
2. Paste it in an SMB share (mine is password protected, not sure if it matters)

OBSERVED RESULT
The error message "Access denied. Could not write to smb://hostname/path/to/dir/." appears.

EXPECTED RESULT
The file is copied.
