Bug ID: 399635
Summary: Discover crashed when launched from "Updates" widget
Product: Discover
Version: 5.12.6
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: mike.spa...@gmail.com
Target Milestone: ---
Application: plasma-discover (5.12.6)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-36-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I saw that the "Updates" widget on my notification area had a blue dot. I
clicked it to launch Discover so that I could apply the updates. The Discover
window displayed briefly (about 2 seconds) in an incomplete state, and then
went away. A crash handler popped up just before the Discover window
disappeared.
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".
