Thanks for taking your time to report this issue and help making Ubuntu better.
I can confirm the issue based on the description https://bugs.launchpad.net/ubuntu/+source/xdg-desktop-portal-kde/5.10.4-0ubuntu1. I suppose this is a copy'n'paste issue, and as you mention should probably be xdg-desktop-portal-kde.
