            Bug ID: 391499
           Summary: KGPG crashes on setting trust level for self keypair
           Product: kgpg
           Version: 17.12.2
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: k...@opensource.sf-tec.de
          Reporter: k...@mva.name
  Target Milestone: ---

Application: kgpg (17.12.2)
 (Compiled from sources)
Qt Version: 5.9.4
Frameworks Version: 5.43.0
Operating System: Linux 4.15.4 x86_64
Distribution: "Gentoo GNU/Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Set trust level fo own keys to "Absolute". Then it freezed, and then I pressed
"Cancel", that, in turn, caused crash.

The crash can be reproduced every time.

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