monitor not detected by GCM after upgrade

[Federico Bruni <fedelogy gmail com>]

Hi all

I'm on Debian testing.
After an upgrade to gnome 3.4.2 my monitor profile is not loaded anymore and, most importantly, I can't see the monitor in the list of devices of GCM (just the printers).

How can I debug this problem?

gnome-color-manager: 3.4.2-1
colord: 0.1.21-1
libxrandr2: 2:1.3.2-2

I'm using nouveau drivers and this video card:

01:00.0 VGA compatible controller: NVIDIA Corporation G86 [GeForce 8500 GT] (rev a1)

Thanks in advance,
Federico
