Frameworks Version: 5.32.0
Operating System: Linux 4.8.0-44-generic x86_64
Distribution: KDE neon User Edition 5.9

-- Information about the crash:
- What I was doing when the application crashed:
Clicked around the network display in the panel. Nothing out of the ordinary. Listened to music, which has a taskbar icon (clementine). Redshift enabled.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
