Same here. 
After inserting a cd-rom with images, selecting f-spot makes f-spot appear for a moment after which it dies. 
I tried to import manually, but selecting "import" from the file-menu kills f-spot.

I ran f-spot like this:
f-spot --debug

The program 'f-spot' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 7286 error_code 16 request_code 136 minor_code 7)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I tried adding the --sync flag but the result was the same.

Next, I tried
mdb /usr/bin/f-spot
Mono Debugger
(mdb) run

after this line, nothing. Mdb just sits there.
