Bug 365860

Application: plasmashell (5.5.5)
 (Compiled from sources)
Qt Version: 5.6.1
Operating System: Linux 4.6.4-gentooTessares x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
 Just activate the VPN for the office. It is based on Google authenticator with openvpn: I get a small window asking me to enter the 6-digits code and crashes (the window stays there and I can enter the code and connect the VPN.)

- Custom settings of the application:
This always happens when activating the VPN. I can provide more info on that if needed.
I use:
 net-misc/networkmanager-openvpn-1.0.8
 net-misc/networkmanager-1.0.12-r1
 kde-frameworks/networkmanager-qt-5.21.0

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
