I never used it either, as I use Plasma.

AFAIK, it should be used as platform plugin by Qt5 applications automatically
when you install it (after logging out/in).
Then you should be able to configure the appearance of Qt5 applications with
the included tool "qt5ct".

The crash occurs with the QtCurve style at least.

I don't know whether it is actually reproducible with qt5ct though, or only
with the Plasma platform plugin. (I may try that later, I actually don't even
use Tumbleweed)
