font management

[Glenn Holmer]

System settings -> Font -> Font management doesn't work for me: no
fonts listed for "All Fonts", "Personal Fonts", or "System
Fonts";
trying to add one gives "Unable to start backend".

Additionally, KFontView still shows flat lines and a few pixel droppings
instead of the font.

Fedora 22, all patches applied. GeForce GTX 650, nouveau driver. Anyone
else seeing this?
