Bug ID: 403841
Summary: Kgpg crashes when changing a key level of trust
Product: kgpg
Version: 17.12.3
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@opensource.sf-tec.de
Reporter: m...@protonmail.com
Target Milestone: ---
Application: kgpg (17.12.3)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-45-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Changing the level of trust of one of my keys to the highest one.
- Unusual behavior I noticed:
After clicking in Apply or Ok buttons, Kgpg enters in an endless loop and
doesn't respond to any command any more.
If I click the Cancel button, Kgpg crashes.
The crash can be reproduced every time.
-- Backtrace:
Application: KGpg (kgpg), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
