Calligra now provides translations as part of the main source tarball (previously this was separate in calligra-l10 tarball)
The translations are now all in calligra-data and Breaks/Replaces have been put in place to remove the old calligra-l10n-* packages as they contain conflicting files. The new calligra is now installable, however there is a system notification pestering the user to install the old calligra l10n packages.

This is due to a script in kubuntu-notification-helper which needs fixed.
