Bluetooth stopped working between 12.10 beta 2 and now (days before 12.10 release)

[Steven Roose]

I upgraded to Ubuntu 12.10 when beta 2 was released. Untill a week after I did, my Bluetooth worked normally. I was using it daily, so I know it was doing just fine. I do a system update multiple times a day and since one of those, my bluetooth stopped working.
Some of the problems are:
- After I open the bluetooth-applet (from gnome-bluetooth) and I want to slide the ON/OFF switch to ON, it stays on OFF. When I try a second time, it stays at ON.

- If I scan for devices (and I have another visible device next to it) it just stays scanning forever without finding anything. (I know bluetooth is on because I can see my computer on the other device.)

- If I turn off bluetooth from the applet or from the top bar, it stays on. I stay seeing it on other devices. When I turn it back on and off some times, it finally gets turned off.

I use a MacBook Pro i5 2.53GHz 15" 2010 in 64-bit.

I filed this for gnome-bluetooth, but probably it's caused by an error in some underlying bluetooth package. I can find the following in my update history:

- Mon Oct 1 17:31:20 2012
  Upgraded the following packages:
    libbluetooth3 (4.101-0ubuntu5) to 4.101-0ubuntu6
  Installed the following packages:
    libbluetooth-dev (4.101-0ubuntu6)

- Mon Oct 1 18:42:04 2012
  Upgraded the following packages:
    gir1.2-gnomebluetooth-1.0 (3.5.92-0ubuntu1) to 3.6.0-0ubuntu1
    gnome-bluetooth (3.5.92-0ubuntu1) to 3.6.0-0ubuntu1
    libgnome-bluetooth11 (3.5.92-0ubuntu1) to 3.6.0-0ubuntu1
  Installed the following packages:
    bluetooth (4.101-0ubuntu6)

Will a fix be released before the official Ubuntu 12.10 release?

Same probleme on amd zacate 'e-350' netbook, i just bought a BT mouse, but i can't pair.

Scan is running indefinitely via UI (android device detect more than 10 bt devices around)

rklill scan or inq gives no results. (bluethoot test is passing as per "system test" app in ubuntu)

BT can't be deactivated from the applet.
