Hi,
I'm having the same problem, but I'm on Ubuntu (19.04).
It crashes with a segmentation fault, and the same messages as Simon reported:
QQmlComponent: Created graphical object was not placed in the graphics scene.
terminate called after throwing an instance of 'std::runtime_error'
what(): bad zip
Aborted (core dumped)
Any update from the QA team?
Regards,
Thomas
