Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-97-generic x86_64
Distribution: Ubuntu 16.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was using my laptop to test guest Wifi network. The laptop was connected to the guest network and I was not doing anything on it. On a separate desktop computer I was making changes to my router config and when done I rebooted the router. At the exact time I rebooted the router this crash occurred on my laptop. I thought this was a strange coincidence so I restarted sddm service on laptop, connected to guest wifi again, and rebooted the router using the desktop again. Same thing happened and plasma crashed on laptop. 

Then I rebooted the laptop just to make sure. Connected to guest wifi again, rebooted router, and it still happened. 

Looks like plasma cannot handle an ungraceful loss of WiFi connection.    

- Unusual behavior I noticed:
Plasma auto restarted but I was unable to use task bar to switch between applications. That is why I restarted sddm service. I was surprised that it crashed when I was not doing anything on the laptop.
