Bug 361238

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
I apply OK without incidents a network profile using the Network Manager in the task bar. Then, I try to apply a VPN profile. I don't try to modify anything, and I don't have any "strange" config at vpn profile: IPs, usernames, passwords. It wasn't happening before, then one day with LEAP it just started happening every time without exceptions, using any of the vpn tunnels I have.

The crash can be reproduced every time.

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