When I am connecting a bluetooth headset (tried different ones) and switch from Headset to Handsfree mode, gnome crashes. It looks like a wireplumber crash leding to a coredump. Honestly, apart from this error log, I have no idea how I may solve this or debug it further - apart from switching to pulseaudio as test - which I did not yet do (no time yet to check it further). I tried different bluetooth devices as well as the current kernels 6.17 and 6.18.
I noticed the same problem today and could pin it down to wireplumber. After downgrading wireplumber and libwireplumber to version 0.5.12-1 the problem is gone, but that can only be a temporary solution. As I’m currently working I didn’t have much time for searching a solution. I would also be interested to know how to debug further when coredumping occurs.
Edit:
I found this related gnome issue
So for now it’s best to stay on wireplumber 0.5.12-1 until they solve it.
Thanks for reporting this issue and for the solution.
It would be very interesting to know how did you manage to pin down the reason to wireplumber, as a mean of learning. I was out of ideas as GNOME kept crashing, there were no ways to give a command or do anything. Thanks
I only use my wireless headset for video conferences and the last time I had one was in mid december. My system is using btrfs with automatic snapshot creation when updating with pacman. So first I tried to find out with which update the problem began. Then, knowing it had something to do with bluetooth and sound, I looked at the packages in that update (Testing Update 2026-01-01). As there were just a few, I was pretty sure, that wireplumber would be that package. So I used the downgrade command to downgrad it, made a reboot and was happy again.
