Bluez 5.71 bluetoothd coredump on a2dp suspend
Description:
Connecting to a voice call with a Bluetooth headset that triggers wireplumber to switch the bluetooth profile from a2dp -> hsp/hfp causes a coredump in bluetoothd, disconnecting the bluetooth headset instead.
Observed with Bose QuietComfort 35 I headphones.
Does not reproduce after downgrading bluez / bluez-libs / bluez-utils 5.71-1 -> 5.70-2.
