How do I retrieve movies and audio files from my Canon PowerShot S5 IS camera?

Shotwell only sees the pictures. Mounting the camera via "Places > Canon Digital Camera" and then clicking twice on the resulting desktop icon yields this error:

could not display "gphoto2://[usb:001,002]/"

There is nothing in /media.

update: output of sudo fdisk -l

Partition table entries are not in disk order

Solution: install gphotofs, then Nautilus shows camera contents similar to a standard usb storage device (though note that gphotofs does not yet support adding to or deleting contents).
