-- Information about the crash:
- What I was doing when the application crashed:
Just let it idle for some time.  Sometimes it would crash just putting there.  Sometimes it would crash when entering power saving mode.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma 桌面 shell (plasma-desktop), signal: Aborted
