Application: plasmashell (5.18.5)

Qt Version: 5.15.0
Frameworks Version: 5.70.0
Operating System: Linux 5.6.14-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

I was to send archived data to a Windows 10 machine via Bluetooth and Plasma had a quite high chance crashing there right before the "Select the device to send to" window pop up. Many attempts was made before it finally worked.

- Unusual behavior I noticed:

My laptop also had difficulty connecting to the desktop Windows machine, which however was solved by removing and pairing with the Windows machine again.

The crash can be reproduced sometimes.

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