Comment 1 Nicolas Fella 2026-01-14 13:53:30 UTC
Thank you for your bug report!

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), as this version of the KDE software no longer receives updates or maintenance from KDE, and so it's possible that the bug exists only in Debian at this point.
Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.

Thanks for understanding!
