Bug ID: 432266
Summary: Discover crashes few seconds after loading
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: justinf7...@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 5.3.0-64-generic x86_64
Distribution: Ubuntu 19.10
-- Information about the crash:
- What I was doing when the application crashed:
I had just opened the application and after it began loading up sources and
returning and error, it crashes. It happens every time.
- Custom settings of the application:
The sources.list file has been manipulated, restoration back to normal did not
resolve the issue, so I tried to replace it with the one from the source, also
did not work. The software source " deb http://deb.playonlinux.com/ ubuntu
main" has been added and appears to be the main cause.
The crash can be reproduced every time.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
