Bug ID: 413808
Summary: DIscover crash on open
Product: Discover
Version: 5.17.2
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: lei...@leinir.dk
Reporter: damien....@gmail.com
CC: aleix...@kde.org
Target Milestone: ---
Application: plasma-discover (5.17.2)
Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-19-generic x86_64
Distribution: Ubuntu 19.10
-- Information about the crash:
- What I was doing when the application crashed:
I was broswing the internet with firefox, then decided to check for updates.
- Unusual behavior I noticed:
When loading, the discover window was overlayed with a clipped portion of the
active internet page in Firefox. I have noticed this behaviour on Discover load
previously, however it did not end in a crash in that instance.
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".
