Sentry Crash Report:

Description ryangrg422 2019-11-10 16:03:13 UTC 
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".
