Bug 374587

Application: kgpg (16.11.90)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

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

Kgpg freshly installed (opensuse leap 42.2). Crashed just after the keys were generated and crashes every time since then, even after a new login or a reboot.

The crash can be reproduced every time.

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