Yes, thanks to some awesome testers picking this up.

This may take some some to get to the release pocket from proposed, as the libreoffice autopkgtests triggered by a kio upload take 4-10 hrs to run.

kio 5.113.0-0ubuntu2 has migrated to the noble release pocket, and I have repun the daily iso to pick that up. So marking this as fixed.
