f-spot: Can't crop raw images

Note: Originally reported via email to the ubuntu-users mailing list.

If I import my raw photos from Canon 350D, .CR2 files. Then all goes
well until I try to crop the photo.

Received Exception. "The requested feature is not implemented" Unable
to save photo blah.CR2

I can send you a raw photo if required but they are about 12Mb!

I assume it is failing to save back as a raw photo should it give the
option to save as a jpg?
