Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-51-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
Started a corporate vpnc connection using network manager widget and the plasma-shell crashed. 

I started the connection using the popup menu and when the manager asked me for my password, the plasma-shell crashed. After plasma-shell restart, I disconnected and restarted the connection but, this time, there was no crash. The crash doesn't affect the vpn connection (it started normally).

I'll update the ticket if I detect a new crash and I can remember what I was doing before starting the vpn connection.

The crash can be reproduced sometimes.

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