No longer existing packages are still in the apt repository

Tim, I was surprised when I found out that packages like tdebase-kio-trinity are still available in the apt repository, although it has been replaced by a more than three months ago. These packages now causing problems when updating from 3.5.13.x to nightly-builds. How is it possible that these packages not disappeared a long time ago? How to fix it? Besides, I noticed that the package ubuntu-trinity-rename-meta is in the build-deps and is not part of tde-packaging (probably could be named simply trinity-rename-meta, and should be included in the main repository). I think that the version of this dummy package should be set to 14.0.0, because otherwise they can not help with the transition => packages are in conflict with renamed packages. Slavek
