Same here: Combo mouse/keyboard MX5500 with bluetooth receiver.
I also got the dialog box asking me to grant access:
Device 'Logitech MX5500 Keyboard' (00:07:61:B5:67:C9) wants access to the service '00001124-0000-1000-8000-00805f9b34fb'.
I had time to click on "Grant" but it didn't do anything, my keyboard still doesn't work.
