            Bug ID: 414004
           Summary: Installation from other source
           Product: Discover
           Version: 5.17.2
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: discover
          Assignee: lei...@leinir.dk
          Reporter: ryan_j_geo...@outlook.com
                CC: aleix...@kde.org
  Target Milestone: ---

Application: plasma-discover (5.17.2)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.0.0-32-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
Installation of Vivaldi from Vivaldi Technologies AG.
During installation the user (myself) was unable to access other portions of
the discover application to view if updates of other software, or view
applications that maybe needed on the system.
The application forcibly crashed and thus cancelled the installation of
Vivaldi.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
