Application: plasmashell (5.14.5) Qt Version: 5.11.3 Frameworks Version: 5.54.0 Operating System: Linux 4.19.0-5-amd64 x86_64 Distribution: Debian GNU/Linux 10 (buster) -- Information about the crash: - What I was doing when the application crashed: I unlocked widgets to add one to the desktop. I then open the widgets sidebar with desktop still in view, I then drag a Folder View widget out to the desktop, in order to place it. Before placing it, I changed my mind and wanted to undo and so I dragged back the widget to the sidebar, but the Activities Manager sidebar showed up because I have it pinned to my left screen edge. I then kept hovering there thinking I could potentially switch Activities while holding the widget so I place it in my desired Activity's desktop and that's when the crash occured. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
