Color from gnome-control-center does nothing when pressed Calibrate button

[Jose Luis Tirado]

I try to calibrate my monitor using a i1Display LT using the Color configuration app from the gnome-control-center. The Calibrate...button is disabled until I connect the device, that becomes enabled. But then when pressed does nothing. No action, no error message, nothing.
If I launch the app from a terminal I get the following error when the button is pressed:

txelu@txelu-acer:~$ gnome-control-center color

(gnome-control-center:4790): GLib-CRITICAL **: g_variant_unref: assertion `value != NULL' failed

(gnome-control-center:4790): color-cc-panel-WARNING **: failed to install required component: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.PackageKit was not provided by any .service files

I'm using a fresh install of ubuntu Precise Pangolin completely updated.

Status changed to 'Confirmed' because the bug affects multiple users.

Just in case this could help when I try to manually get information on the calibration device using colormgr I get the following error:

txelu@txelu-acer:~$ sudo colormgr get-sensors
Object Path: /org/freedesktop/ColorManager/sensors/i1_pro

(colormgr:3025): Cd-WARNING **: Failed to lock sensor: Failed to Lock: GDBus.Error:org.freedesktop.ColorManager.Failed: cannot lock non-native driver

So I can see the system correctly identifies my calibration device as a i1_pro but it has no access to it...
