Bug#827016: plasma-desktop: unable to install simultaneously kde-l10n-* and plasma-desktop-data

[mando <mando@april.org>]

Package: plasma-desktop-data
Version: 4:5.6.4-2
Severity: important

Dear Maintainer,

I recently updated my Debian stretch.
Unfortunately, plasma-desktop depends on plasma-desktop-data which breaks every available kde-l10n-* translation package currently available.

I tried, without success:
- to find an alternative translation package to translate KDE apps
- to switch the application language via Help > Switch application language: only english (american) is available
- to specify my native language (e.g. French) via System settings

Currently:
- Some KDE apps (e.g. kmail, konqueror, kopete, korganizer) are displayed in english.
- Some parts of KDE remains in english (for instance kickoff menu, systemconfig, konsole, amarok, dolphin).

However, every KDE apps should be displayed in the appropriate language.

Thanks, best regards!
