I have just experienced this problem in a dist-upgrade from Hardy to Intrepid.
The camera is iPhone gphoto2://[usb:008,002]/DCIM/100APPLE
Pressing "Open F-spot Phot manager" button in Nautilus gives error alert:
Error connecting to camera
Received error "could not lock the device" while connecting to camera.
