Description Máirín Duffy 2011-12-31 23:23:45 UTC 
I bought a QP201 calibration card for my Canon SLR. I'm running Fedora 16, and there are no updates available for gnome-color-manager or any seemingly-related color management tools I have installed.

I took a picture of the QP201 with my Canon. I attached the Canon to my computer via USB.

I opened up gnome-color-manager. I selected my Canon in the device list and clicked on 'Calibrate...'. I tried 'Quick', 'Normal', and 'Accurate' during separate attempts. I selected the QP201 card under calibration targets. I clicked next. I get a screen that says:

"[header] Failed to calibrate  [dialog text] failed to match display"

Then I noticed this error happens if I select the integrated webcam on my laptop as well. So it seems unrelated to the camera. (At first I thought maybe Shotwell was locking the Canon, but that the bug happens for the webcam too I think eliminates that possibility.)
