Gross, the crash is super deep, but does ultimately have something in Kirigami: #22 0x00007f1e10e4c4fe in (anonymous namespace)::Q_QGS_s_delegateCache::innerFunction()::Holder::~Holder() () from /usr/lib64/qt5/qml/org/kde/kirigami.2/libkirigamiplugin.so
hmm, delegateCache may suggest DelegateRecycler, but we don't have any Holder class.
Holder is in Qt. I imagine it's the one here: qtbase/corelib/global/qglobalstatic.h:86 struct Holder { QtPrivate::QSlotObjectBase *obj; ~Holder() { obj->destroyIfLastRef(); } } holder = { slot }; Q_UNUSED(holder);
