      Description of problem:

      After a successful pairing of a Lenovo TrackPoint Keyboard II via Gnome settings, connection will be made, and bluetoothd will enter a segfault loop. Whenever the keyboard reconnects, the segfault appears.

      Version-Release number of selected component (if applicable):

      rpm -aqv | grep blue
      bluez-libs-5.56-8.el9.x86_64
      bluez-5.56-8.el9.x86_64
      bluez-obexd-5.56-8.el9.x86_64
      gnome-bluetooth-libs-3.34.5-3.el9.x86_64
      gnome-bluetooth-3.34.5-3.el9.x86_64
      NetworkManager-bluetooth-1.36.0-5.el9_0.x86_64

      How reproducible:

      Reproducible with this keyboard and el9, tried with Asus BT-500 dongle (rtl) and Intel bt, same.

      Steps to Reproduce:
      1. Pair a TrackPoint keyboard II
      2. Connect it.

      Actual results:

      Will occurs on each reconnection after bluetoothd recovery (same address):

      Expected results:

      Keyboard should just work

      Additional info:

      Can't reproduce on Fedora, can reproduce on CentOS 9 Stream.

      No issue with other kind of devices I have at hand (headset, mice etc...)
