I can confirm the crash, but only this way: 1. Have top and bottom panel, with only task manager in bottom panel 2. Enter edit mode 3. Add analog clock to top panel 4. Start dragging the clock widget from top panel to bottom panel 5. Plasmashell gets confused and crashes Also I could not open the video, I don't know why.
