Oh ok !
Sorry for my english, I will try to be exhaustive in my experiences with
bluetooth that I frequently use to connect my phone.
For completeness I wish to inform you that my bluetooth device is a
common Broadcom dongle :
ID 0a5c:2101 Broadcom Corp. A-Link BlueUsbA2 Bluetooth
I tried several times to remove the bluetooth dongle while doing the
transfer to simulate a mistake, the browser windows (if opened)
disapperas as like as the bluetooth symbol from the task bar but the
file transfer hangs with an awful 100% Nautilus CPU usage, until I kill
it.
For you informations the Kernel shows :

The bluez stack seems to work properly. When I open a new connection by the
OBEX browser and run hcitool, I can see the following situation :
$ hcitool con
Connections:
< ACL XX:XX:XX:XX:XX:XX handle 11 state 1 lm MASTER AUTH ENCRYPT
But only :
$ hcitool con
Connections:
when the dongle is disconnected as well as is should be.
As this behaviour does not appears for example when I transfer a file to an USB
disk, I think that Nautilus does not receive the right signals from the
bluetooth obex module, during the file transfer.
Thanks for now.
