Public bug reported:
After the latest updates, GNOME Shell crashes when a Bluetooth
handsfree headset connects (HFP/HSP). This started on 2026-01-19 and is
reproducible every time.
Timeline (MSK):
- 2026-01-19 19:12:39: GNOME Shell crashes with signal 6.
- 2026-01-19 19:13:05: GNOME Shell crashes again immediately after restart.
Relevant log evidence:
- GNOME Shell abort:
Gvc:ERROR:../subprojects/gvc/gvc-mixer-stream.c:535:gvc_mixer_stream_get_port:
code should not be reached
- Bluetooth/HFP failures around crash:
bluetoothd: profiles/audio/avdtp.c:handle_unanswered_req() No reply to
SetConfiguration request
bluetoothd: Hands-Free Voice gateway ... Transport endpoint is not
connected (107)
- Kernel Bluetooth error:
Bluetooth: hci0: SCO packet for unknown connection handle 257
- PipeWire/WirePlumber restarted around the crash window (seen in user
journal).
Steps to Reproduce:
1. Boot and log into GNOME (Wayland).
2. Connect Bluetooth handsfree headset (HFP/HSP).
Expected Result:
Headset connects and GNOME Shell remains stable.
Actual Result:
GNOME Shell aborts (signal 6) shortly after headset connects; session
restarts; crash repeats on reconnect.
