Operating System: Linux 4.2.6-1-CHAKRA x86_64
Distribution: "Chakra"

-- Information about the crash:
- What I was doing when the application crashed: I undocked my pc (Dell Latitude E5550) from its dock to plug it to a hdmi external display.

- Unusual behavior I noticed: The resolution of my laptop's screen changed to become 4:3 (instead of 16:9)

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
