Thanks for the bug report. Unfortunately, these versions of Konsole and Plasma are no longer maintained by KDE. Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting). 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.
