Created attachment 136209 [details] New crash information added by DrKonqi plasmashell (5.12.9) using Qt 5.9.5 - What I was doing when the application crashed: I powered the computer on, with autologin enabled. - Unusual behavior I noticed: Computer froze for a few seconds, almost completely unresponsive (most likely because the error occurred and kde had to be restarted). However, some things were still getting rendered during this unresponsiveness, a slow flashing was present. Afterwards, everything worked as expected. -- Backtrace (Reduced): #6 0x00007f585c64a268 in QQuickAnimatorProxyJob::sceneGraphInitialized() () from /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5 #7 0x00007f5858b330c2 in QObject::event(QEvent*) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #8 0x00007f5859b0b83c in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #9 0x00007f5859b13104 in QApplication::notify(QObject*, QEvent*) () from /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #10 0x00007f5858b038d8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
