journalctl-output between enabling Bluetooth in the system tray applet and the
last message related to the attempted connection
SUMMARY
'kded5' process crashes and core dump is generated when connecting a
Playstation 5 Dualsense Controller via Bluetooth to my Archlinux desktop. This
happens most of the times but not always. I am not able to see any pattern in
this behavior. This doesn't happen either if the controller is connected using
a USB cabel.
STEPS TO REPRODUCE
1. Make sure you have the controller and a supported Bluetooth adapter
('TP-Link UB500' USB adapter in my case) available and the controller is
paired.
2. Press the 'PlayStation' button in order to connect the controller.
OBSERVED RESULT
The controller is listed as 'connected' in the Bluetooth applet for a fraction
of a second. Then, all system tray icons disappear and reappear a fraction of a
second later. The Bluetooth tray applet closes during this process and then
reopens, telling that Bluetooth is disabled. There is no Bluetooth connection
to the controller established.
EXPECTED RESULT
The controller should be listed as connected, no process should crash.

The Dualsense Controller has a fully supported Touchpad. Given that the
journalctl log contains outputs that specifically refer to a touchpad and no
other touchpad is connected, this might be related to the bug.
