Description Tim Van den Langenbergh 2017-02-11 19:45:34 UTC 
Application: kgpg (16.12.1)

Qt Version: 5.7.1
Frameworks Version: 5.30.0
Operating System: Linux 4.9.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I was raising the trust level of my preferred key from "Unknown" to "Ultimate", as I noticed I had forgotten to do so when I imported it.

The crash can be reproduced every time.

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