Application: plasma-discover (5.12.6) Qt Version: 5.9.5 Frameworks Version: 5.44.0 Operating System: Linux 4.15.0-33-generic x86_64 Distribution: Ubuntu 18.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: Clicked on the update icon on the taskbar, there were 36 updates. The application window appeared with the waiting icon. Then crashed. Things to note. I hadn't rebooted since the last update and because of that the screensaver would say it's broken. May have nothing to do with the Discover crash. -- Backtrace: Application: Discover (plasma-discover), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
