Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: #0 0x00007ffff5f63154 in QScreen::geometry() const () at /usr/lib/libQt5Gui.so.5 #1 0x000055555558e318 in () #2 0x000055555558e784 in () #3 0x000055555558ed43 in () #4 0x000055555558ee19 in () #5 0x00007ffff5abe0d1 in () at /usr/lib/libQt5Core.so.5 #6 0x00007ffff7eed763 in KQuickAddons::QuickViewSharedEngine::statusChanged(QQmlComponent::Status) () at /usr/lib/libKF5QuickAddons.so.5 #7 0x00007ffff5abe0d1 in () at /usr/lib/libQt5Core.so.5 #8 0x00007ffff7c27186 in KDeclarative::QmlObject::statusChanged(QQmlComponent::Status) () at /usr/lib/libKF5Declarative.so.5 Could you please install debug symbols for plasma, plasma-framework and Qt, reproduce the crash, and attach a new symbolicated backtrace?
