Ok, a short follow up:

I can do tethered shooting with gphoto2, simply

$ gphoto2 --capture-tethered

This will download each image to the current folder, and delete it from the 
camera. A script can be called to display the image, that is yet to do, since 
I shoot in RAW. Gwenview can not display thumbs from my RAW images, it seems. 
I could use showfoto, but that would cause the images to be converted, which 
takes time.

Maybe it is possible to use dbus to show the images in digikam or showfoto as 
they are shot. It would be fun to have the option inside digikam, and images 
renamed and put into folder as desired by user, and of course displayed as 
shot.

Using gphoto2, I can also capture an image immediately, or capture-and-
download:

$ gphoto2 --capture-image
$ gphoto2 --capture-image-and-download

This means that the capture menu item should be fixable, I believe.

The preview fetching does not do anything, trying it, I get something like 
this:

[anders at kamelon t]$ gphoto2 --get-thumbnail 3
Hjemhenter 'IMG_2890.CR2' fra mappe '/store_00010001/DCIM/129EOS7D'...         
Hjemhenter 'IMG_2890.CR2' fra mappe '/store_00010001/DCIM/129EOS7D'...

("Hjemhenter" means something like fetching). But no file is available in the 
cwd after that.

So maybe digikam isn't alone having this problem...
