Thanks for the bug report. Unfortunately, k4dirstat is not developed by KDE. 

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting).
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.
