Application: plasmashell (5.5.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-301.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I added a new WPA2 Enterprise Network connection and when I clicked on the open file dialogue button to add a ssl certificate, plasmashell crashed.

#356718 seems to be a duplicate, but the crash reporting GUI seems to be broken and I can't add this as duplicate

The crash can be reproduced every time.

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