Hello, I'm running Pulseaudio 12.0 on Arch Linux.

When I try to switch my Bluetooth headphones to the AD2P profile PulseAudio is
crashing with the following in the log:

This may not be a problem in PulseAudio but rather in some libraries, and
started with latest package updates.

Can you please give some advice to how debug this issue?
