Sentry Crash Report:

Description alexanromano 2020-02-26 13:22:25 UTC 
Application: plasmashell (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.5.5-200.fc31.x86_64 x86_64
Distribution: Fedora 31 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
I was closing multiple Notes widgets using right click -> alt+N to (remove notes)

- Unusual behavior I noticed:
Notification system got slow to a point where it crashed (I assume). The screen went black, the Notes came back in random desktops/places and all the pending notifications appeared at the same time

- Custom settings of the application:
I am using the Sweet Kvantum theme with icons, fonts and colors from the built-in marketplace. Only the kvantum theme is external.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
