I've got a Canon 30D (USB PTP mode), and I'd like to be able to use gthumb to pull RAW mode files off the device when it's connected, rather than having to resort to gphoto on the command line. This could then allow me use gthumb to automatically prompt for import of files, without duplicating effort to get the RAW files off with gphoto.

It'd be nice if a thumbnail could be displayed (eg: using dcraw), but if they can't it's no real problem - the problem is more getting the files off the device. Perhaps instead of a thumbnail of the pic in question simply a "This file format cannot be displayed" icon or something similar to that effect.

Currently using Breezy, but I'm willing to try special builds or backports to test this sort of functionality.
