Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk

-- Information about the crash:
- What I was doing when the application crashed:
打开桌面设置后连续两次更改桌面布局（从“桌面”改为“文件夹视图”，应用后再改回“桌面”并应用），点击确定后回到桌面，点击桌面左上角按钮（三条横杠）导致桌面崩溃。
- Custom settings of the application:
桌面扩展“红移（redshift）”
自定义的壁纸
The crash can be reproduced every time.
