Package: bluez
Version: 5.49-1
Severity: grave
I'm trying to use Bluetooth through the GNOME UI, but bluetoothd keeps
crashing:
$ systemctl status bluetooth
● bluetooth.service - Bluetooth service
Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor
preset: enabled)
Active: failed (Result: signal) since Tue 2018-05-08 14:55:38 BST; 1min 23s

Docs: man:bluetoothd(8)
Process: 13542 ExecStart=/usr/lib/bluetooth/bluetoothd (code=killed,
signal=SEGV)
Main PID: 13542 (code=killed, signal=SEGV)
Status: "Running"
$ sudo dmesg | grep bluetooth
[333848.278325] bluetoothd[13542]: segfault at 8 ip 000055983cd7e4d0 sp
00007ffca41fd988 error 4 in bluetoothd[55983cd0a000+10d000]
There seems to be a race condition involved, because if I run
bluetoothd under gdbserver, it usually doesn't crash until I toggle
Bluetooth on and off once or twice.
Anyway, I got the following backtrace:
Program received signal SIGSEGV, Segmentation fault.
