What I was doing when the application crashed:
Plasma crashed after I deleted a system monitor widget from my desktop.

I have three activities, plain (no widgets just for wallpaper), main (Folder
view and trash can) and info (For comics and weather report and other info). I
had the system load applet in my panel, i moved it to the desktop and deleted.
It resulted in plasma crash.
