Application: plasmashell (5.18.5)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.3.0-51-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
I've opened a folder from desktop, later on I tried to move three .mp3 files (that were also located on desktop) into the opened folder but Plasma crashed. The background turned black (dolphin and other apps were still open) and after a few seconds, Plasma started again; so I tried to move the same files again but Plasma crashed in the same way; this time showing the Crash Reporting Assistant. Files were not moved.

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