[Pkg-utopia-maintainers] Bug#1050916: pipewire death secondary to general protection fault in libspa-bluez5.so

Thu Aug 31 12:38:59 BST 2023

Package: libspa-0.2-bluetooth
Version: 0.3.79-1

Hello, I noticed this line in dmesg after a Bluetooth audio loss:
[96307.727270] traps: wireplumber[2128] general protection fault ip:7f7b0145d29f sp:7f7b03ffe950 error:0 in libspa-bluez5.so[7f7b01449000+b1000]

I had a audio playing in Firefox, which I believe should have been the only app using audio. The computer was essentially idle at the moment it crashed, I wasn't touching the audio/bluetooth settings or the headset.
The bluetooth headset is a WH-1000XM4 using A2DP/LDAC. I'm running trixie/sid, up-to-date as of today.
