Tribler segfaults

Tribler chrashes and is not useable. Usually when I try to click on something. This is on Manjaro, installed with AUR.

I have done a series of pip installs suggested from AUR (en) - tribler , for it to even start.

From terminal:
QBackingStore::endPaint() called with active painter; did you forget to destroy it or call QPainter::end() on it?
QPaintDevice: Cannot destroy paint device that is being painted
