Status changed to 'Confirmed' because the bug affects multiple users.

[Igor V. Kovalenko (i-garrison)]

This could be a problem in pulseaudio native backend, provoked by numerous reconnections between bluez and headset.

If verbose log from pulseaudio daemon can be collected for this crash, I think it is worth to file an issue in pulseaudio tracker here https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/ with verbose log attached.

[Daniel van Vugt (vanvugt)]

No crashes since 15.0 so consider it fixed.
