kde4 vs plasma5 khelpcenter

[Rex Dieter]

In case other packagers find the pitfall fedora did...

Folks are probably aware that both kde-applications (in kde-runtime) and 
plasma-5.x include versions of khelpcenter.  We, like some other 
distros, created a separate khelpcenter (sub)package from kde-runtime. 
The pitfall we hit was that kde-applications version (15.04.0) was 
higher than plasma (5.3.x).

And, unfortunately, kde4 khelpcenter doesn't work with kf5 applications. 
  For example, see:
https://bugs.kde.org/show_bug.cgi?id=349570

Fedora recently fixed that (by introducing an epoch to khelpcenter-5.x 
packaging), so the plasma5 version has precedence.
