Dear all,
I experienced a SEGFAULT from bluez 5.56-1
on Arch Linux - linux 5.11.1.arch1-1:
It happened during having A2DP connection with pipewire-git 0.3.22.76.g08445d2c-1.
This is the backtrace:

This looks like it is related to AVRCP not A2DP, does pipewire
register a player?

Hi Luiz,
Thanks for your reply!
This is beyond my knowledge. By guessing I looked into the D-Bus system-
in the system bus, so if you mean under org.bluez
/org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX/org.bluez.MediaControl1/Player,
that property is not set, so I think there is no registration.
I would come back to you and this issue if I experienced another time.
I changed something, deactivated the MPRIS proxy systemd service.
Regards,
Tobias
