Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.8.0-49-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: I tried looking through the other duplicates as there seemed to have similar titles, but the nature of their crashes is selecting a wifi connection.. Mine only does it only when I want to select a VPN location. I was able to add location with a import cert option before that is now gone.  My VPN provider has instructions to do it the old way to add new profiles, but now I am unable to add them.. When I  dont crash after connecting to a VPN, my connection would last like 5 minutes and quit.   Of all the other times this has crashed, the crash report keeps reporting that there is not enough info to give to you guys, so I home my explination is clear enough. 

- Unusual behavior I noticed:

- Custom settings of the application:

The crash can be reproduced every time.
