What I was doing when the application crashed:
I opened desktop setting and tried to get new wallpapers. When the wallpapers preview came i clicked on multiple Install buttoms. After some time, the "get new wallpapers" window got automatically closed. When i again tried to open the "get new wallpaper" window, the plasma desktop crashed generating this report.
