Application: plasmashell (5.4.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was adding a new network via the tray and then editing the settings to get rid of the kwallet promts (All users may connect to this network). 
When the connection was being established I got this segfault. 
- Unusual behavior I noticed:
Kwallet popping up all the time although I never configured it and there's also no section in systemsettings to turn it off. At least not under User Details. This is a freshly installed OpenSUSE Leap 42.1

Thanks in advance!

-- Backtrace:
