Bug ID: 394294
Summary: Crash after clicking "update" in system tray
Product: Discover
Version: 5.12.5
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: wowhellm...@gmail.com
Target Milestone: ---
Application: plasma-discover (5.12.5)
Qt Version: 5.10.0
Frameworks Version: 5.46.0
Operating System: Linux 4.13.0-41-generic x86_64
Distribution: KDE neon User Edition 5.12
-- Information about the crash:
- What I was doing when the application crashed:
I just tried to update system and discover crashed 2 seconds after clicking
"update" button in notification.
Now it immediately crashes every time i try to open it, even if i run it from
launcher.
I haven't messed with it any configuration files, everything is by default.
The crash can be reproduced every time.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
