Filed upstream bug 
https://bugs.kde.org/show_bug.cgi?id=377425

re-confirming still FTBFS with latest upstream 17.04.0 release (and master/ branch has no relevant changes either)

*** Bug 1478133 has been marked as a duplicate of this bug. ***

Echoing comment added to upstream report:

Confirmed still an issue with kde-apps 17.08.1 release as well.

Notice if this isn't fixed soon, fedora will likely have to drop this package from it's collection.

I ran fedpkg retire, fyi. Maybe something went wrong

OK, confirmed it definitely didn't work last time, let's hope this one sticks.
