Summary: Discover Crash When Updating
Product: Discover
Version: 5.12.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: lordcube...@tutamail.com
Target Milestone: ---
Application: plasma-discover (5.12.5)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-22-lowlatency x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I selected the update option from update plasmoid on my panel and the app would
crash shortly after opening. It would crash before it displayed the needed
updates on screen.
- Custom settings of the application:
I know I have a few non-working softwear repos on my apt list.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
