blueman-applet crashes on resume from suspend (D-Bus race condition)

[MalikMlitat]

Version: 2.3.5-3build1 (Ubuntu 24.04 noble)

Description:
blueman-applet crashes intermittently when the system resumes from suspend.
The crash appears to be a race condition where blueman tries to communicate
with bluetoothd via D-Bus before the bluetooth service has fully restarted.

Steps to reproduce:

1. Suspend the system (e.g. close laptop lid)
2. Resume from suspend
3. blueman-applet crashes — Ubuntu reports an internal error for /usr/bin/blueman-applet

Expected: applet reconnects to bluetoothd gracefully after resume
Actual: applet crashes with a Python/GLib exception

Workaround: systemd-sleep hook that kills and restarts blueman-applet 3s after resume

Related: #325, #488, #2521

---

Once you've run the two sudo commands for the sleep hook, the workaround should kick in on your next resume. Let me know if the crash persists after that.

Could you try if #3282 helps?
