Images don't display in f-spot

["Cliff Pratt" <enkiduonthenet gmail com>]

f-spot 0.4.3.1. running on Ubuntu 8.04.

When I open f-spot I see small image of all my pictures. If I right
click one and select "Open with..." I get "No applications available".
I have a number of image viewers available on my system including EOG.
If I double click an image I see the 'film strip' at the top and what
looks like a monitor screen with the corner turned up - presumably an
error icon.

I've search the archives but the nearest thing I can find is this:

http://mail.gnome.org/archives/f-spot-list/2008-May/msg00000.html

But the 'Preferred Applications' applet doesn't have anything to do
with images.

I've looked at the "Preferences" options in f-spot, but none seem to apply.

Does anyone have any ideas?

Cheers,

Cliff
