Bug 374509

Application: kgpg (16.12.0)

Qt Version: 5.7.0
Frameworks Version: 5.29.0
Operating System: Linux 4.4.0-57-generic x86_64
Distribution: KDE neon User Edition 5.8

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

- Custom settings of the application:
I have an existing directory .gnugpg with my configuration.
If I remove it the crash does not occur.

May be related to fixed bugs 373408 or 371410, but I have kgpg 16.12.0 from kde neon.

The crash can be reproduced every time.

-- Backtrace:
Application: KGpg (kgpg), signal: Segmentation fault
