When I attach my camera, I get a pop-up dialog inviting me to import photos. The following processes are running:-

/bin/sh /usr/bin/gnome-volume-manager-gthumb \
 /org/freedesktop/Hal/devices/usb_device_4a9_3101_noserial_if0
gthumb --import-photos

The camera is a Canon EOS 5D, and as I shoot almost exclusively in RAW, the gthumb dialog shows nothing available for import - only the 2 stray JPEG images on the card. I've rebuilt gthumb from source, and linked against libopenraw - this has enabled thumbnail previews of CR2 files already on disk, but there appears to be no way to import them. Using gphoto2 from the command line works fine, of course.

This makes gthumb pretty much unusable for me, unfortunately. Is there an easy way to get round it? It appears as though all the support needed is already there, it's just filtering out CR2 images from the list.
