Comment 2 for bug 862992

I can make the Calibrate button do something, by installing gnome-color-manager through Software Centre (search for Color Calibration), however the process does not complete.

Once gnome-color-manager is installed, clicking Calibrate takes me through a series of dialogues, ending with a 'Performing Calibration' message.

Briefly a grey box is displayed in the centre of my screen, before the calibration process aborts.

The following error is shown in terminal output:

~$ gnome-control-center color
(gcm-calibrate:4198): Gcm-WARNING **: VTE: could not screenscrape: Setting up the instrument
(gcm-calibrate:4198): GdkPixbuf-CRITICAL **: gdk_pixbuf_loader_write: assertion `error == NULL || *error == NULL' failed

I am using a Pantone Huey calibration device.
