Bug 373196

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-47-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I have dockerswarm running on my dev-machine. It creates about 5 network adapters for my environment. If I close docker then I can switch network no problem. But with docker active then NetworkManager kills Plasma, or vice versa.

- Custom settings of the application:
create a docker swarm with docker 1.12 or above. I have no running containers and it still crashes.
KDE installed by default  as I'm running Kubuntu.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
