Comment 1 Halla Rempt 2018-08-13 17:58:04 UTC 
Hm... This does show a real problem, but I'm not sure where we have a sig/slot connection in different threads:

QLayout: Attempting to add QLayout "" to QWidget "", which already has a layout
QMetaObject::indexOfSignal: signal selectionChanged() from KoSelectedShapesProxy redefined in KisSelectedShapesProxy
QMetaObject::indexOfSignal: signal selectionChanged() from KoSelectedShapesProxy redefined in KisSelectedShapesProxy
ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread 0x0xa2832b0. Receiver '' (of type 'KisImage') was created in thread 0x0x25d9930", file kernel/qcoreapplication.cpp, line 58

However... _Why_ is Qt built with asserts enabled? That shouldn't be done in release builds, should it?

You will have to ask Aleix Pol, the maintainer of the KDE runtime for flatpak.
Comment 3 Halla Rempt 2018-08-13 18:17:34 UTC 
I will. Tomorrow -- since we're now both in Vienna, for Akademy.
Comment 4 Albert Astals Cid 2018-09-18 18:01:49 UTC 
It seems meanwhile that this has been fixed (or so says the flathub bug)
