Bug ID: 419051
Summary: Discover won't open
Product: Discover
Version: 5.16.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: lei...@leinir.dk
Reporter: javama...@gmail.com
CC: aleix...@kde.org
Target Milestone: ---
Application: plasma-discover (5.16.5)
Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.0.0-38-generic x86_64
Distribution: Ubuntu 19.10
-- Information about the crash:
- What I was doing when the application crashed: In the tray I have a
notification that updates are available, I click it, Discover starts to open,
then crashes.
If I use the application menu to start Discover, it also starts to open, then
crashes.
This has been happening for over a month now. Preventing my system from
updating normally.
The crash can be reproduced every time.
-- Backtrace:
Application: Discover (plasma-discover), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
