Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.3.5-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed:
I clicked "Connect" next to an OpenVPN network name.

The crash sometimes also happens when I do the same to connect to a wlan network.

NetworkManager does connect to a network, it's just plasma that I need to reboot.

The crash isn't actually 100% reproducible, it's more like 80%.

The crash can be reproduced every time.

-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
