testing migrations
This package is part of the ongoing testing transition known as kdepim-26.08.
Please avoid uploads unrelated to this transition, they would
likely delay it and require supplementary work from the release
managers. On the other hand, if your package has problems
preventing it to migrate to testing, please fix them
as soon as possible.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
