What's wrong with my f-spot?

[pihou <philyer gmail com>]

I finally decided to take the time to manage my pictures properly, and,
as I'm starting to use ubuntu edgy, f-spot seems to be the software I
need.
Unfortunately, I confront some trouble----my f-spot, which was OK
yesterday, cannot be started now. Codes are below:

***********************CODE***************************
$ f-spot
