-- Information about the crash:
Plasma crashed while I simulate the network. There are few applications open namely Google Chrome, Dolphin and Konsole. I don't know if packet tracer caused the crash, but because I'm working on it, I suspect it caused the crash.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
