Bug Description

Binary package hint: gnome-user-share

On Jaunty, package gnome-user-share_2.25.92-0ubuntu2

There appears to be a race condition on suspend/resume and hibernate/thaw which causes obexpushd and obexftp to not get correctly shutdown on suspend/hibernate and it attempts to restart them on resume, which fails. This makes any subsequent attempt to transfer files to the system via bluetooth fail.

I've traced this to src/user-share.c consolekit_init() method and sessionchanged_cb(). When the condition fails, sessionchanged_cb gets an "Active" on suspend/hibernate rather than "Inactive" which causes the services to not get stopped. It gets another "Active" on resume/thaw and then all hell breaks loose.

I've attached a patch which simplifies the dbus code to register a callback which is passed the active/inactive state, thus eliminating the race condition. This same method is used in netbook-launcher.

Added comment in upstream bug report on steps to reproduce. This bug was filed originally filed almost 1 year ago, so I have not verified if still exists with the latest code.

Can somebody tell me why ubuntu PC (12.04 ) can't automatically receive files over Bluetooth and save them with no user interaction ?
I already install obexpushd with the command : $sudo apt-get install obexpushd
After installed it , i create a file : /etc/init/obexpushd.conf and add the following code in this file .
chdir /home/USERNAME
exec obexpushd -n
start on startup
$sudo initctl reload-configuration
$sudo start obexpushd
But it seems can't automatically receive files over Bluetooth .
