DBus assertion failures after upgrade to BlueZ 5.62

Hi folks,

After upgrading to BlueZ 5.62 on Arch Linux, intermittently bluetoothd crashes 
like this:

     bluetoothd[161733]: dbus[161733]: arguments to dbus_message_new_method_call() were incorrect, assertion "destination == NULL || _dbus_check_is_valid_bus_name (destination)" failed in file dbus-message.c line 1364.
     bluetoothd[161733]: This is normally a bug in some application using the D-Bus library.
     bluetoothd[161733]: profiles/audio/media.c:release_endpoint() Couldn't allocate D-Bus message
     bluetoothd[161733]: Stopping SDP server
     bluetoothd[161733]: Exit

This behaviour started after upgrading from 5.61. No upgrade to dbus, which is 
still at 1.12.20 and has been for some time.

Any ideas?

Thanks,

Chris
