Bug#846660: [kded5] should depend on libkf5screen-bin

[Maximiliano Curia <maxy@debian.org>]

¡Hola Reuben!

About the subject, kded is a loader, it shouldn't depend on the parts that the 
plugins depend on.

The bin part was split back in libkf5kscreen 5.5, and kscreen depends on 
the bin part since then.

Also, kscreen is the package that provides the kded module for kscreen, so
the corresponding dependency is already there.

This looks like a mess. I can't really parse this. But I wouldn't be surprised 
if some package in a different archive is blocking, or overriding one of the 
provided by Debian. Please, check which version of kscreen, libkf5kscreen7, 
libkf5kscreen-bin version you have installed, where they come from, and the 
dependencies of that packages.

The kscreen 4:5.8.4-1 from our repositories has the dependency:
Depends: kde-cli-tools, plasma-framework, qml-module-qtgraphicaleffects, libc6 (>= 2.14), libkf5configcore5 (>= 4.97.0), libkf5configwidgets5 (>= 4.96.0), libkf5coreaddons5 (>= 4.100.0), libkf5dbusaddons5 (>= 4.97.0), libkf5globalaccel5 (>= 5.0.0), libkf5i18n5 (>= 4.97.0), libkf5screen-bin (>= 4:5.6.2~), libkf5screen7 (>= 4:5.8.0), libkf5widgetsaddons5 (>= 4.96.0), libkf5xmlgui5 (>= 4.96.0), libqt5core5a (>= 5.7.0), libqt5dbus5 (>= 5.4), libqt5gui5 (>= 5.7.0), libqt5qml5 (>= 5.0.2), libqt5quick5 (>= 5.2.0), libqt5widgets5 (>= 5.4), libstdc++6 (>= 4.1.1)

Happy hacking,
