Installing kopete-data removes all kde-l10n packages

[Mark Fraser]

I Kubuntu 19.04 if I install kopete and kopete-data I am no longer able 
to install any kde-l10n packages.

aptitude why-not kde-l10n-engb
i   kopete      Depends kopete-data (= 4:18.12.3-0ubuntu2)
iBA kopete-data Breaks  kde-l10n-engb (< 4:18.04.0~)

If this is a bug, where do I report it?
